'Summer' in the Bible

And when David was a little past the top of the hill, behold, Ziba the servant of Mephibosheth met him, with a couple of asses saddled, and upon them two hundred loaves of bread, and an hundred bunches of raisins, and an hundred of summer fruits, and a bottle of wine.

And the king said unto Ziba, What meanest thou by these? And Ziba said, The asses be for the king's household to ride on; and the bread and summer fruit for the young men to eat; and the wine, that such as be faint in the wilderness may drink.
