“Let us therefore root this out quickly, and let us fall down before the Master and entreat him with tears, that he may show himself propitious and be reconciled to us and may restore us to the seemly and pure conduct that belongs to our love of the brothers. For this is a gate of righteousness opened to life, as it is written: "Open to me the gates of righteousness, that I may enter in thereby and praise the Lord. This is the gate of the Lord; the righteous shall enter in thereby." Seeing then that many gates are opened, this is that gate that is in righteousness, even that which is in Christ, whereby all are blessed who have entered in and direct their path in holiness and righteousness, performing all things without confusion. Let a person be faithful, let him be able to expound a deep saying, let him be wise in the discernment of words, let him be strenuous in deeds, let him be pure; for so much the more ought he to be lowly in mind, in proportion as he seems to be the greater; and he ought to seek the common advantage of all, and not his own.”

“Our father Jacob too prayed at Bethel and saw the gate of heaven opened, with a ladder going up on high. This is a symbol of our Savior that Jacob saw: the gate of heaven is Christ, in accordance with what he said: "I am the gate of life; every one who enters by me shall live forever." David too said, "This is the gate of the Lord, by which the righteous enter." Again, the ladder that Jacob saw is a symbol of our Savior, in that by means of him the just ascend from the lower to the upper realm. The ladder is also a symbol of our Savior's cross, which was raised up like a ladder, with the Lord standing above it; for above Christ is the Lord of all, just as the blessed apostle said: "The head of Christ is God." Now Jacob called that place Bethel; and Jacob raised up there a pillar of stone as a testimony, and he poured oil over it. Our father Jacob did this too in symbol, anticipating that stones would receive anointing—for the peoples who have believed in Christ are the stones that are anointed; just as John says of them: "From these stones God is able to raise up children for Abraham." For in Jacob's prayer the calling of the nations was symbolized.”

“"Open me," he says, "the gates of righteousness" [Psalm 118:19]. Behold, we have heard of the gates. What is within? "That I may," he says, "go into them, and give thanks unto the Lord." This is the confession of praise full of wonder, "even unto the house of God, in the voice of joy and confession of praise, among such as keep holiday:" this is the everlasting bliss of the righteous, whereby they are blessed who dwell in the Lord's house, praising Him for evermore.”

“The stone which the builders refused,.... This is not Zerubabel, according to the sense of some Jews, as Theodoret suggests; nor the people of Israel, as Jarchi and Kimchi; nor David, as the Targum, which paraphrases the words, "the child the builders despised was among the sons of Jesse, and deserved to be appointed a king and a governor.'' He doubtless was a type of Christ, and there was some shadow of what is here said in him: he was refused by all the tribes but Judah; Ishbosheth, the son of Saul, was set upon the throne, though afterwards all Israel and Judah united in making David king, Sa2 2:8. But the Messiah is intended, as some ancient Jewish writers (e) own, and Jarchi himself elsewhere (f) confesses; and which is certain from the quotation and application of this passage to Christ, in Mat 21:42, Act 4:11; who is compared to a stone for his strength and duration; and because of his usefulness in the spiritual building of the church, as a foundation and corner stone; See Gill on Mat 21:42. Him the Jewish builders refused; their political ones, their rulers, that believed not on him; the princes of this world, that rose up against him and crucified him; even those who were the support of their civil state, and the maintainers of it: but more especially their ecclesiastical builders, the chief priests, Scribes, and Pharisees, who built the people, or directed them to build on their carnal privileges, the traditions of the elders, and their own legal righteousness. These refused to receive Jesus as the Messiah, and to believe in him; they refused to own and honour him as King of Zion; they refused his doctrines and ordinances; they refused to hear him preach, or suffer others to hear him; they refused to make use of him in the spiritual building, either to preach him themselves, or allow others to do it; they rejected him with contempt; they set him at nought, and preferred a thief and a robber to him; is become the head stone of the corner; Christ is the corner stone, that unites elect angels and elect men together, Jews and Gentiles, Old and New Testament saints, saints above and below, saints in all ages and places; and he is the head stone, or chief corner stone, for strength and beauty, and the head of the corner; or of persons most eminent, who are sometimes called the corner, Jdg 20:2. Christ is exalted above all; he is the head of principalities and powers, the angels; he is made higher than the kings of the earth; and is the head of the body, the church, an head both of eminence and influence.

“Justice. Of the temple, where the undefiled Israelites alone can enter, (Psalm xiv. 1.) or the land of Judea, Isaias xxvi. The Fathers explain it of the Church, and of heaven, to which none can be admitted, who have not departed in the communion of saints, (St. Chrysostom; St. Augustine) having walked in the narrow path. (Eusebius) — Christ styles himself the way, (Haydock) and the gate . (Berthier) (Apocalypse xxii. 14.) — Formerly penitents were not allowed to be present during all the Mass; and heretics, &c., are cut off from the bosom of the Church. (Calmet) — The just here beg for instruction, which they promise to follow. (Worthington)”

“The gates of the holy place are so styled, because just men shall enter by them to perform acts of duty to God : but the holier temple, the church, seems to be specially meant.”

“The gates of the Temple are called gates of righteousness because they are the entrance to the place of the mutual intercourse between God and His church in accordance with the order of salvation. First the "gates" are spoken of, and then the one "gate," the principal entrance. Those entering in must be "righteous ones;" only conformity with a divine loving will gives the right to enter. With reference to the formation of the conclusion Psa 118:19, vid., Ew. 347, b. In the Temple-building Israel has before it a reflection of that which, being freed from the punishment it had had to endure, it is become through the mercy of its God. With the exultation of the multitude over the happy beginning of the rebuilding there was mingled, at the laying of the foundation-stone, the loud weeping of many of the grey-headed priests. Levites, and heads of the tribes who had also seen the first Temple (Ezr 3:12.). It was the troublous character of the present which made them thus sad in spirit; the consideration of the depressing circumstances of the time, the incongruity of which weighed so heavily upon their soul in connection with the remembrance of the former Temple, that memorably glorious monument of the royal power of David and Solomon. (Note: Kurtz, in combating our interpretation, reduces the number of the weeping ones to "some few," but the narrative says the very opposite.) And even further on there towered aloft before Zerubbabel, the leader of the building, a great mountain; gigantic difficulties and hindrances arose between the powerlessness of the present position of Zerubbabel and the completion of the building of the Temple, which had it is true been begun, but was impeded. This mountain God has made into a plain, and qualified Zerubbabel to bring forth the top and key-stone (האבן הראשׁה) out of its past concealment, and thus to complete the building, which is now consecrated amidst a loud outburst of incessant shouts of joy (Zac 4:7). Psa 118:22 points back to that disheartened disdain of the small troubles beginning which was at work among the builders (Ezr 3:10) at the laying of the foundation-stone, and then further at the interruption of the buidling. That rejected (disdained) corner-stone is nevertheless become ראשׁ פּנּהּ, i.e., the head-stone of the corner (Job 38:6), which being laid upon the corner, supports and protects the stately edifice - an emblem of the power and dignity to which Israel has attained in the midst of the peoples out of deep humiliation. In connection with this only indirect reference of the assertion to Israel we avoid the question - perplexing in connection with the direct reference to the people despised by the heathen - how can the heathen be called "the builders?" Kurtz answers: "For the building which the heathen world considers it to be its life's mission and its mission in history to rear, viz., the Babel-tower of worldly power and worldly glory, they have neither been able nor willing to make use of Israel...." But this conjunction of ideas is devoid of scriptural support and without historical reality; for the empire of the world has set just as much value, according to political relations, upon the incorporation of Israel as upon that of every other people. Further, if what is meant is Israel's own despising of the small beginning of a new ear that is dawning, it is then better explained as in connection with the reference of the declaration to Jesus the Christ in Mat 21:42-44; Mar 12:10., Act 4:11 (ὑφ ̓ ὑμῶν τῶν οἰκοδομούντων), Pe1 2:7, the builders are the chiefs and members of Israel itself, and not the heathen. From Pe1 2:6; Rom 9:33, we see how this reference to Christ is brought about, viz., by means of Isa 28:16, where Jahve says: Behold I am He who hath laid in Zion a stone, a stone of trial, a precious corner-stone of well-founded founding - whoever believeth shall not totter. In the light of this Messianic prophecy of Isaiah Psa 118:22 of our Psalm also comes to have a Messianic meaning, which is warranted by the fact, that the history of Israel is recapitulated and culminates in the history of Christ; or, according to Joh 2:19-21 (cf. Zac 6:12.), still more accurately by the fact, that He who in His state of humiliation is the despised and rejected One is become in His state of glorification the eternal glorious Temple in which dwelleth all the fulness of the Godhead bodily, and is united with humanity which has been once for all atoned for. In the joy of the church at the Temple of the body of Christ which arose after the three days of burial, the joy which is here typically expressed in the words: "From with Jahve, i.e., by the might which dwells with Him, is this come to pass, wonderful is it become (has it been carried out) in our eyes," therefore received its fulfilment. It is not נפלאת but נפלאת, like הבאת in Gen 33:11, קראת from קרא = קרה in Deu 31:29; Jer 44:23, קראת from קרא, to call, Isa 7:14. We can hear Isa 25:9 sounding through this passage, as above in Psa 118:19., Isa 26:1. The God of Israel has given this turn, so full of glory for His people, to the history. (Note: The verse, "This is the day which the Lord hath made," etc., was, according to Chrysostom, an ancient hypophon of the church. It has a glorious history.) He is able now to plead for more distant salvation and prosperity with all the more fervent confidence. אנּא (six times אנּה) is, as in every other instance (vid., on Psa 116:4), Milra. הושׁיעה is accented regularly on the penult., and draws the following נא towards itself by means of Dag. forte conj.; הצליחה on the other hand is Milra according to the Masora and other ancient testimonies, and נא is not dageshed, without Norzi being able to state any reason for this different accentuation. After this watchword of prayer of the thanksgiving feast, in Psa 118:26 those who receive them bless those who are coming (הבּא with Dech) in the name of Jahve, i.e., bid them welcome in His name. The expression "from the house of Jahve," like "from the fountain of Israel" in Psa 68:27, is equivalent to, ye who belong to His house and to the church congregated around it. In the mouth of the people welcoming Jesus as the Messiah, Hoosanna' was a "God save the king" (vid., on Ps 20:10); they scattered palm branches at the same time, like the lulabs at the joyous cry of the Feast of Tabernacles, and saluted Him with the cry, "Blessed is He who cometh in the name of the Lord," as being the longed-for guest of the Feast (Mat 21:9). According to the Midrash, in Psa 118:26 it is the people of Jerusalem who thus greet the pilgrims. In the original sense of the Psalm, however, it is the body of Levites and priests above on the Temple-hill who thus receive the congregation that has come up. The many animals for sacrifice which they brought with them are enumerated in Ezr 6:17. On the ground of the fact that Jahve has proved Himself to be אל, the absolutely mighty One, by having granted light to His people, viz., loving-kindness, liberty, and joy, there then issues forth the ejaculation, "Bind the sacrifice," etc. The lxx renders συστήσασθε ἑορτὴν ἐν τοῖς πυκάζουσιν, which is reproduced by the Psalterium Romanum: constituite diem solemnem in confrequentationibus, as Eusebius, Theodoret, and Chrysostom (although the last waveringly) also interpret it; on the other hand, it is rendered by the psalterium Gallicum: in condensis, as Apollinaris and Jerome (in frondosis) also understand it. But much as Luther's version, which follows the latter interpretation, "Adorn the feast with green branches even to the horns of the altar," accords with our German taste, it is still untenable; for אסר cannot signify to encircle with garlands and the like, nor would it be altogether suited to חג in this signification. (Note: Symmachus has felt this, for instead of συστήσασθε ἑορτὴν ἐν τοῖς πυκάζουσιν (in condensis) of the lxx, he renders it, transposing the notions, συνδήσατε ἐν πανηγύρει πυκάσματα. Chrysostom interprets this: στεφανώματα καὶ κλάδους ἀνάψατε τῷ ναῷ, for Montfaucon, who regards this as the version of the Sexta, is in error.) Thus then in this instance A. Lobwasser renders it comparatively more correctly, although devoid of taste: "The Lord is great and mighty of strength who lighteneth us all; fasten your bullocks to the horns beside the altar." To the horns?! So even Hitzig and others render it. But such a "binding to" is unheard of. And can אסר עד possibly signify to bind on to anything? And what would be the object of binding them to the horns of the altar? In order that they might not run away?! Hengstenberg and von Lengerke at least disconnect the words "unto the horns of the altar" from any relation to this precautionary measure, by interpreting: until it (the animal for the festal sacrifice) is raised upon the horns of the altar and sacrificed. But how much is then imputed to these words! No indeed, חג denotes the animals for the feast-offering, and there was so vast a number of these (according to Ezra loc. cit. seven hundred and twelve) that the whole space of the court of the priests was full of them, and the binding of them consequently had to go on as far as to the horns of the altar. Ainsworth (1627) correctly renders: "unto the hornes, that is, all the Court over, untill you come even to the hornes of the altar, intending hereby many sacrifices or boughs." The meaning of the call is therefore: Bring your hecatombs and make them ready for sacrifice. (Note: In the language of the Jewish ritual Isru-chag is become the name of the after-feast day which follows the last day of the feast. Ps 118 is the customary Psalm for the Isru-chag of all מועדים.) The words "unto (as far as) the horns of the altar" have the principal accent. In v. 28 (cf. Exo 15:2) the festal procession replies in accordance with the character of the feast, and then the Psalm closes, in correspondence with its beginning, with a Hodu in which all voices join.”
