Revelation 18:4

“And I heard another voice from heaven, etc.] Either of another, or of the same angel, or rather of God, or Christ himself, since the persons addressed are called his people: saying, come out of her, my people; meaning either his elect ones, till now uncalled, being such whom God had chosen for his people, and were so by virtue of the covenant of grace, were given to Christ as his people, and were redeemed by him, though, till this call, in an unconverted state; or else such who had been secretly called by the grace of God, but had not made a public profession of the Gospel, nor bore an open testimony against the Romish idolatry; for as the Lord had a righteous Lot in Sodom, and saints where…”

“Come out of her, my people--quoted from Jer 50:8; Jer 51:6, Jer 51:45. Even in the Romish Church God has a people: but they are in great danger; their only safety is in coming out of her at once. So also in every apostate or world-conforming church there are some of God's invisible and true Church, who, if they would be safe, must come out. Especially at the eve of God's judgment on apostate Christendom: as Lot was warned to come out of Sodom just before its destruction, and Israel to come from about the tents of Dathan and Abiram. So the first Christians came out of Jerusalem when the apostate Jewish Church was judged. "State and Church are precious gifts of God. But the State being…”

“And I heard another voice from heaven - He does not say whether this was the voice of an angel, but the idea seems rather to be that it is the voice of God. Come out of her, my people - The reasons for this, as immediately stated, are two: (a)That they might not participate in her sins; and, (b)That they might not be involved in the ruin that would come upon her. The language seems to be derived from such passages in the Old Testament as the following: “Go ye forth of Babylon, flee ye from the Chaldeans, with a voice of singing,” Isaiah 48:20. “Flee out of the midst of Babylon, and deliver every man his soul; be not cut off in her iniquity,” Jeremiah 51:6. “My people, go ye out of the midst…”

“And I heard another voice - Of Christ, whose people, secretly scattered even there, are warned of her approaching destruction. That ye be not partakers of her sins - That is, of the fruits of them. What a remarkable providence it was that the Revelation was printed in the midst of Spain, in the great Polyglot Bible, before the Reformation! Else how much easier had it been for the Papists to reject the whole book, than it is to evade these striking parts of it. Revelation 18:5”

“18:4-8 This second poetic response (see study note on 18:1-24) is a warning from heaven to flee the doomed city. 18:4 Do not take part in her sins: Association with the evil city could lead to being identified with it in punishment and even involved with it in its sins (see Gen 13:8-13; 19:1-29; cp. Jer 51:6, 45).”

“Come: Gen 19:12, Gen 19:13; Num 16:26, Num 16:27; Isa 48:20, Isa 52:11; Jer 50:8, Jer 51:6, Jer 51:45, Jer 51:50; Mat 24:15, Mat 24:16; Co2 6:17 partakers: Psa 50:18; Mat 23:30; Ti1 5:22; Jo2 1:11 Revelation 18:5”
