Now while he was not yet gone back, he said, Go back also to Gedaliah the son of Ahikam the son of Shaphan, whom the king of Babylon hath made governor over the cities of Judah, and dwell with him among the people: or go wheresoever it seemeth convenient unto thee to go. So the captain of the guard gave him victuals and a reward, and let him go.
While he was not yet gone back - parenthetical. When Jeremiah hesitated where it would be best for him to go, Nebuzar-adan proceeded to say, 'Go, then, to Gedalish,' etc. (not as the English version, "Go to back also"), if thou preferrest (as Nebuzaradan inferred from Jeremiah's hesitancy) to stop here rather than go with me.
Victuals - (Isaiah 33:16, "Bread shall be given him").
Reward - rather a present. This must have been a seasonable relief to the prophet, who probably lost his all in the siege.
