JER 40:10

10 As for me, I will stay [here] at Mizpah to be your representative to the [officials from] Babylonia who come to [talk with] us. But you should [return to your towns, and eat the things that are produced on your land]. Harvest the grapes and the fruit [that ripen in] the ◄summer/hot season► and the olives, [make wine and olive oil,] and store it.”
