Jeremiah 40:9-10

9Gedaliah son of Ahikam, the son of Shaphan, took an oath to reassure them and their men. “Do not be afraid to serve the Babylonians,” he said. “Settle down in the land and serve the king of Babylon, and it will go well with you. 10I myself will stay at Mizpah to represent you before the Babylonians who come to us, but you are to harvest the wine, summer fruit and olive oil, and put them in your storage jars, and live in the towns you have taken over.”
