21:4 Thus saith the LORD God of Israel; Behold, I will {b} turn back the weapons of war that [are] in your hands, with which ye fight against the king of Babylon, and [against] the Chaldeans, who besiege you outside the walls, and I will assemble them into the midst of this city.
(b) That is, from your enemies to destroy yourselves.
21:1-10 When the siege had begun, Zedekiah sent to ask of Jeremiah respecting the event. In times of distress and danger, men often seek those to counsel and pray for them, whom, at other times, they despise and oppose; but they only seek deliverance from punishment. When professors continue in disobedience, presuming upon outward privileges, let them be told that the Lord will prosper his open enemies against them. As the king and his princes would not surrender, the people are exhorted to do so. No sinner on earth is left without a Refuge, who really desires one; but the way of life is humbling, it requires self-denial, and exposes to difficulties.
