| Barnes' Notes on the Bible Shout - i. e., spoken of the war-cry. So in Isaiah 42:13, where God is compared to a warrior, it is said He shall shout (the King James Version cry), i. e., raise the war-cry. Site hath given her hand - The sign of submission (compare 1 Chronicles 29:24 margin). Foundations - Or, buttresses. The Septuagint: "battlements."
Clarke's Commentary on the BibleShout against her round about - Encompass her with lines and with troops; let none go in with relief, none come out to escape from her ruin.
Gill's Exposition of the Entire BibleShout against her round about,.... As soldiers do when they make an assault upon a place, to encourage one another, and dismay the besieged; just as the Israelites did when they surrounded Jericho: she hath given her hand; submitted to the conqueror, and sued for mercy. The Targum is, "she is delivered into her hand;'' the hand of the Persians, by two princes of Babylon, who went off to Cyrus, and showed him how to take the city; or rather it was delivered by Zopyrus into the hands of Darius: her foundations are fallen, her walls are thrown down; not at the taking of it by Cyrus, but afterwards by Darius; for this respects the conclusion of its destruction, which was progressive and gradual: for it is the vengeance of the Lord: which he decreed, threatened, and took, and that on account of his people, who had been ill treated here; so the Targum, "for it is the vengeance of the people of the Lord:'' and her enemies are called upon to take vengeance upon her; as she hath done, do unto her; that is, to execute the Lord's vengeance, of which the Persians were the instruments; and who were to go according to the law of retaliation, which is a just one; to do to Babylon as she had done to Jerusalem, and other places, she had utterly destroyed. These words seem to be referred to, and much the same are used of mystical Babylon, Revelation 18:6.
Geneva Study BibleShout against her round about: she hath given her hand: her foundations are fallen, her walls are thrown down: for it is the vengeance of the LORD: take vengeance upon her; as she hath done, do unto her.
Wesley's Notes 50:15 Given her hand - Acknowledging themselves overcome, and yielding. As she hath done - Unmerciful men find no mercy.
Jamieson-Fausset-Brown Bible Commentary15. Shout-Inspirit one another to the onset with the battle cry. given . hand-an idiom for, "submitted to" the conquerors (1Ch 29:24, Margin; La 5:6). as she hath done, do unto her-just retribution in kind. She had destroyed many, so must she be destroyed (Ps 137:8). So as to spiritual Babylon (Re 18:6). This is right because "it is the vengeance of the Lord"; but this will not justify private revenge in kind (Mt 5:44; Ro 12:19-21); even the Old Testament law forbade this, though breathing a sterner spirit than the New Testament (Ex 23:4, 5; Pr 25:21, 22).
Matthew Henry's Concise Commentary50:8-20 The desolation that shall be brought upon Babylon is set forth in a variety of expressions. The cause of this destruction is the wrath of the Lord. Babylon shall be wholly desolated; for she hath sinned against the Lord. Sin makes men a mark for the arrows of God's judgments. The mercy promised to the Israel of God, shall not only accompany, but arise from the destruction of Babylon. These sheep shall be gathered from the deserts, and put again into good pasture. All who return to God and their duty, shall find satisfaction of soul in so doing. Deliverances out of trouble are comforts indeed, when fruits of the forgiveness of sin. |
