“"Everlasting joy," says Isaiah, "shall be upon their heads." Well, there is nothing eternal until after the resurrection. "And sorrow and sighing," he continues, "shall flee away." The angel echoes the same to John: "And God shall wipe away all tears from their eyes"; from the same eyes indeed that had formerly wept and that might weep again, if the lovingkindness of God did not dry up every fountain of tears. And again: "God shall wipe away all tears from their eyes; and there shall be no more death," and therefore no more corruption, it being chased away by incorruption, even as death is by immortality. If sorrow, and mourning, and sighing, and death itself assail us from the afflictions both of soul and body, how shall they be removed, except by the cessation of their causes, that is to say, the afflictions of flesh and soul? Where will you find adversities in the presence of God? Where, incursions of an enemy in the bosom of Christ? Where attacks of the devil in the face of the Holy Spirit, now that the devil himself and his angels are "cast into the lake of fire."”

“For the Lamb, which is in the midst of the throne,.... See Rev 5:6; not before the throne, as the great multitude are said to be, Rev 7:9; nor round about it, as the angels in Rev 7:11; but in the midst of it, being equal to him that sits upon it; sitting on the same throne with him, and having the same power and authority, he shall feed them as a shepherd his flock; for this Lamb is a Shepherd, and this great multitude are his flock; whom he will feed in this state, not by his ministers, word, and ordinances, as now; but in person, and with the rich discoveries of himself, and of his love, signified by a feast, by new wine in his Father's kingdom, and his own, and by eating and drinking at his table, in the kingdom appointed by him to his followers; and hence it is they shall never hunger more: or "shall rule them", as the Vulgate Latin version renders it; for the same word signifies "to feed", and "to rule", as a king rules his subjects; Christ will now be visibly King of saints, and King over all the earth, and will reign before his ancients gloriously; and, in these days of his, Judah shall be saved, and Israel shall dwell safely under his power and protection: and shall lead them unto living fountains of water; by "water" is meant the grace, love, and free favour of God in Christ, that pure river of water of life, which proceeds from the throne of God, and of the Lamb, from divine sovereignty; and with which the saints in this state shall be sweetly and fully solaced and refreshed; and hence they shall never thirst more: and this is said to be "living", because not only refreshing and reviving, but because it will last for ever; the love of God is from everlasting to everlasting; and it is signified by "fountains", to denote the abundance of it, even as it will be perceived and enjoyed by the saints now; for these waters will not be only up to the ankles, and knees, but a broad river to swim in, which cannot be passed over; and hither will Christ lead his people, which is, one branch of his office as a Shepherd; and which shows his care of them, and affection for them. And God shall wipe away all tear, from their eyes; or "out of their eyes", as the Alexandrian copy reads; see Isa 25:8. The sense is, that that which is now the occasion of tears will cease, as the sin and corruptions of God's people, which now are the cause of many tears; as also Satan's temptations, the hidings of God's face, and the various afflictions of this life, and the persecutions of the men of the world; there will be no more of either of these; all will be made to cease; see Rev 21:4; and in the room of them full and everlasting joy will take place, Isa 35:10. Mr. Daubuz thinks, that the whole of this chapter belongs to the sixth seal, and that the promises in it are such as were to be accomplished at the opening of the seventh, and do not belong to the millennium state; but had their fulfilment in the times of Constantine, who he supposes is the angel that came from the east, who restrained the persecutors of the church, and introduced a general peace in church and state; and as he came with the seal of the living God, which he understands of the cross of Christ, he put upon his standard, and on the shields of his soldiers, so he sealed the servants of God on their foreheads with it, by allowing them to make a public profession of a crucified Christ, and by protecting them in that profession, even men of all nations, Jews and Gentiles; and particularly he thinks the innumerable palm bearing company may design the council of Nice, gathered by him, which consisted of the representatives of the whole Christian church in the several nations of the world, who had great honour, freedom, and immunities conferred upon them; and that the angels are the Christian magistrates, submitting to the Christian religion, and defending the church, which was now come out of the great tribulation of Heathen persecution, and had temples and places of public worship opened for them; in which they had full liberty to serve the Lord continually, without interruption; and were secure from all affliction and persecution, and were filled with joy and gladness; and the Lamb, by the means of Constantine, as Christ's vicar and servant, he declared himself to be, fed and protected the church in peace and quietness; all which are accomplished during the rest, or "silence", under the next seal; and which I should very readily agree to, since this interpretation carries on the thread of the prophetic history without any interruption, were it not for the description of the palm bearing company, both as to quantity and quality, and the declaration of the happy state of those come out of great tribulation, which I think cannot be made to suit with any imperfect state of the church on earth, without greatly lowering the sense of the expressions used; however, if anyone prefers this exposition to what is given, I am not much averse unto it.

“The Lamb - The Lord Jesus, enthroned with his Father in ineffable glory. Shall feed them - Shall communicate to them every thing calculated to secure, continue, and increase their happiness. Living fountains of water - A spring in the Hebrew phraseology is termed living water, because constantly boiling up and running on. By these perpetual fountains we are to understand endless sources of comfort and happiness, which Jesus Christ will open out of his own infinite plenitude to all glorified souls. These eternal living fountains will make an infinite variety in the enjoyments of the blessed. There will be no sameness, and consequently no cloying with the perpetual enjoyment of the same things; every moment will open a new source of pleasure, instruction, and improvement; they shall make an eternal progression into the fullness of God. And as God is infinite, so his attributes are infinite; and throughout infinity more and more of those attributes will be discovered; and the discovery of each will be a new fountain or source of pleasure and enjoyment. These sources must be opening through all eternity, and yet, through all eternity, there will still remain, in the absolute perfections of the Godhead, an infinity of them to be opened! This is one of the finest images in the Bible. God shall wipe away - In the most affectionate and fatherly manner, all tears from their eyes - all causes of distress and grief. They shall have pure, unmixed happiness. Reader, this is the happiness of those who are washed from their sins. Art thou washed? O, rest not till thou art prepared to appear before God and the Lamb. If these saints had not met with troubles and distresses, in all likelihood they had not excelled so much in righteousness and true holiness. When all avenues of worldly comfort are shut up, we are obliged to seek our all in God; and there is nothing sought from him that is not found in him.”

“The Lamb, which is in the midst of the throne, God and man, shall rule [1] them as a shepherd does his flock. By the Greek, And shall lead them unto fountains of living waters; [2] literally, to the fountains of life of waters; shall bless them with everlasting happiness. (Witham) — He represents the happiness of the saints, under the idea of being exempt from all the wants and evils of this life. For we are not able, according to truth itself, to conceive the happiness that is prepared for us; wherefore we must content ourselves with considering what it is not, rather than what it is. He, nevertheless, seems to compare heaven to a temple or palace, in which we observe ministers and servants all in their proper order, his counsellors (if we may be allowed the expression) and friends seated in presence of their prince, and the souls of the just singing the praises of the Most High. (Car.)”

“in the midst of the throne--that is, in the middle point in front of the throne (Rev 5:6). feed--Greek, "tend as a shepherd." living fountains of water--A, B, Vulgate, and CYPRIAN read, (eternal) "life's fountains of waters." "Living" is not supported by the old authorities. Next: Revelation Chapter 8”
