John Trapp on Jeremiah 40:5

Ver. 5. Now while he was not yet gone back] But yet ſhewed by his lookes or otherwiſe, that he was not willing to go to Babylon: Nebuchadnezzar, Ex ipſo vultu vel ſilentio Jeremiae, &c. who had already ſet his eyes upon him, as ver. 4. perceiving it, ſaid,

So the Captain of the guard gave him victuals] i. e. Neceſſaries for his journey; for he came out of priſon nudus tanquam ex mari, bare and needy.

And a reward] Or, a preſent fit for a Prophet: donum honorarium, ſuch as they uſed to give the Seers, 1 Sam. 9.8. 1 King. 14. and ſuch as he might ſafely and comfortably take, as from God himſelf, who had promiſed it, chap. 15.11.
