The title of this Psalm is brief and simple, and need not detain us; since we know whose resemblance David wore, and since in him we recognise ourselves also, for we too are members of that Body. The whole title is, "To David himself." Let us see then, what is to David himself. The title of the Psalm is wont to tell us what is treated of within it: but in this, since the title informs us not of this, but tells us only to Whom it is chanted, the first verse tells us what is treated of in the whole Psalm, "I will confess to You." This confession then let us hear. But first I remind you, that the term confession in Scripture, when we speak of confession to God, is used in two senses, of sin, and of praise. But confession of sin all know, confession of praise few attend to. So well known is confession of sin, that, wherever in Scripture we hear the words, "I will confess to You, O Lord," or, "we will confess to You," immediately, through habitually understanding in this way, our hands hurry to beating our breast: so entirely are men wont not to understand confession to be of anything, save of sin. But was then our Lord Jesus Christ Himself too a sinner, who says in the Gospel, "I confess to You, Father, Lord of heaven and earth"? He goes on to say what He confesses, that we might understand His confession to be of praise, not of sin, "I confess to You, Father, Lord of heaven and earth, because You have hid these things from the wise and prudent, and hast revealed them unto babes." He praised the Father, he praised God, because He despises not the humble, but the proud. And such confession are we now going to hear, of praise of God, of thanksgiving. "With my whole heart." My whole heart I lay upon the altar of Your praise, an whole burnt-offering of praise I offer to You...."I will confess to You, O Lord, with my whole heart: for You have heard the words of my mouth" [Psalm 138:1]. What mouth, save my heart? For there have we the voice which God hears, which ear of man knows not at all. We have then a mouth within, there do we ask, thence do we ask, and if we have prepared a lodging or an house for God, there do we speak, there are we heard. "For He is not far from every one of us, for in Him we live, and move, and have our being." [Acts 17:27-28] Nought makes you far off from God, save sin only. Cast down the middle wall of sin, and you are with Him whom you ask.

"I will worship toward Your holy Temple" [Psalm 138:2]. What holy Temple? That where we shall dwell, where we shall worship. For we hasten that we may adore. Our heart is pregnant and comes to the birth, and seeks where it may bring forth. What is the place where God is to be worshipped?..."The Temple of God is holy," says the Apostle, "which Temple you are." [1 Corinthians 3:17] But assuredly, as is manifest, God dwells in the Angels. Therefore when our joy, being in spiritual things, not in earthly, takes up a song to God, to sing before the Angels, that very assembly of Angels is the Temple of God, we worship toward God's Temple. There is a Church below, there is a Church above also; the Church below, in all the faithful; the Church above, in all the Angels. But the God of Angels came down to the Church below, and Angels ministered to Him on earth, [Matthew 4:11] while He ministered to us; for, "I came not," says He, "to be ministered unto, but to minister." [Matthew 20:28] ...The Lord of Angels died for man. Therefore, "I will worship toward Your holy Temple;" I mean, not the temple made with hands, but that which You have made for Yourself.

"In what day soever I call upon Thee, do Thou quickly hear me" (ver. 3). Wherefore, "quickly"? Because Thou hast said, "While yet thou art speaking I will say, Lo, here I am." Wherefore, "quickly"? Because now I seek not earthly happiness, I have learnt holy longings from the New Testament. I seek not earth, nor earthly abundance, nor temporal health, nor the overthrow of my enemies, nor riches, nor rank: nought of these do I seek: therefore "quickly hear me." Since Thou hast taught me what to seek, grant what I seek. ...Let us see then what he seeketh, with what right he hath said, "quickly hear me." For what seekest thou, that thou shouldest quickly be heard? "Thou shalt multiply me." In many ways may multiplication be understood. ...For men are multiplied in their soul with cares: a man seemeth to be multiplied in soul, in whom vices even are multiplied. That is the multiplication of want, not of fulness. What then dost thou desire, thou who hast said, "quickly hear me," and hast withdrawn thyself entirely from the body, from every earthly thing, from every earthly desire, so as to say to God, "Thou shalt multiply me in my soul"? Explain yet further what thou desirest. Thou shalt multiply me, saith he, in my soul "with virtue." ...

"Let all the kings of the earth confess to Thee, O Lord" (ver. 4). So shall it be, and so it is, and that daily; and it is shown that it was not said in vain, save that it was future. But neither let them, when they confess to Thee, when they praise Thee, desire earthly things of Thee. For what shall the kings of the earth desire? Have they not already sovereignty? Whatever more a man desire on earth, sovereignty is the highest point of his desire. What more can he desire? It must needs be some loftier eminence. But perhaps the loftier it is, the more dangerous. And therefore the more exalted kings are in earthly eminence, the more ought they to humble themselves before God. What do they do? "Because they have heard all the words of Thy mouth." In a certain nation were hidden the Law and the Prophets, "all the words of Thy mouth:" in the Jewish nation alone were "all the words of Thy mouth," the nation which the Apostle praiseth, saying, "What advantage hath the Jew? Much every way; chiefly because that unto them were committed the oracles of God." These were the words of God. ...What meant Gideon's fleece? It is like the nation of the Jews in the midst of the world, which had the grace of sacraments, not indeed openly manifested, but hidden in a cloud, or in a veil, like the dew in the fleece. The time came when the dew was to be manifested in the floor; it was manifested, no longer hidden. Christ alone is the sweetness of dew: Him alone thou recognisest not in Scripture, for whom Scripture was written. But yet, "they have heard all the words of thy mouth."

"And let them sing in the paths of the Lord, that great is the glory of the Lord" [Psalm 138:5]. Let all the kings of the earth sing in the paths of the Lord. In what paths? Those that are spoken of above, "in Your mercy and Your truth." Let not then the kings of the earth be proud, let them be humble. Then let them sing in the ways of the Lord, if they be humble: let them love, and they shall sing. We know travellers that sing; they sing, and hasten to reach the end of their journey. There are evil songs, such as belong to the old man; to the new man belongs a new song. Let then the kings of the earth too walk in Your paths, let them walk and sing in Your paths. Sing what? That "great is the glory of the Lord," not of kings.

(Hom. xxi. [al. xx.] 1) Many when they read this passage, are perplexed at finding that, whereas Peter was pronounced blessed for having, after our Lord’s miracles and teaching, confessed Him to be the Son of God, Nathanael, who makes the same confession before, has no such benediction. The reason is this. Peter and Nathanael both used the same words, but not in the same meaning. Peter confessed our Lord to be the Son of God, in the sense of very God; the latter in the sense of mere man; for after saying, Thou art the Son of God, he adds, Thou art the King of Israel; whereas the Son of God was not the King of Israel only, but of the whole world. This is manifest from what follows. For in the case of Peter Christ added nothing, but, as if his faith were perfect, said, that he would build the Church upon his confession; whereas Nathanael, as if his confession were very deficient, is led up to higher things: Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? Thou shalt see greater things than these. As if He said, What I have just said has appeared a great matter to thee, and thou hast confessed Me to be King of Israel; what wilt thou say when thou seest greater things than these? What that greater thing is He proceeds to shew: And He saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man. See how He raises him from earth for a while, and forces him to think that Christ is not a mere man: for how could He be a mere man, whom angels ministered to? It was, as it were, saying, that He was Lord of the Angels; for He must be the King’s own Son, on whom the servants of the King descended and ascended; descended at His crucifixion, ascended at His resurrection and ascension. Angels too before this came and ministered unto Him, and angels brought the glad tidings of His birth. Our Lord made the present a proof of the future. After the powers He had already shewn, Nathanael would readily believe that much more would follow.

(Hom. xx) He asks as man, Jesus answers as God: Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee: not having beheld him as man, but as God discerning him from above. I saw thee, He says, that is, the character of thy life, when thou wast under the fig tree: where the two, Philip and Nathanael, had been talking together alone, nobody seeing them; and on this account it is said, that on seeing him a long way off, He said, Behold an Israelite indeed; whence it appears that this speech was before Philip came near, so that no suspicion could attach to Christ’s testimony. Christ would not say, I am not of Nazareth, as Philip told you, but of Bethlehem; in order to avoid an argument: (ἀμφισβητήσιμον λόγον.) and because it would not have been sufficient proof, had He mentioned it, of His being the Christ. He preferred rather proving this by His having been present at their conversation.
