2 The captain of the bodyguard singled out Jeremiah and said to him, "Your God pronounced doom on this place. 3 God came and did what he had warned he'd do because you all sinned against God and wouldn't do what he told you. So now you're all suffering the consequences. 4 "But today, Jeremiah, I'm setting you free, taking the chains off your hands. If you'd like to come to Babylon with me, come along. I'll take good care of you. But if you don't want to come to Babylon with me, that's just fine, too. Look, the whole land stretches out before you. Do what you like. Go and live wherever you wish. 5 If you want to stay home, go back to Gedaliah son of Ahikam, son of Shaphan. The king of Babylon made him governor of the cities of Judah. Stay with him and your people. Or go wherever you'd like. It's up to you." The captain of the bodyguard gave him food for the journey and a parting gift, and sent him off.

Commentary on Jeremiah 40:1-6
(Read Jeremiah 40:1-6)
The captain of the guard seems to glory that he had been God's instrument to fulfil, what Jeremiah had been God's messenger to foretell. Many can see God's justice and truth with regard to others, who are heedless and blind as to themselves and their own sins. But, sooner or later, all men shall be made sensible that their sin is the cause of all their miseries. Jeremiah has leave to dispose of himself; but is advised to go to Gedaliah, governor of the land under the king of Babylon. It is doubtful whether Jeremiah acted right in this decision. But those who desire the salvation of sinners, and the good of the church, are apt to expect better times from slight appearances, and they will prefer the hope of being useful, to the most secure situations without it.
