'Mulberry trees' in the Bible

And David inquired again of God; and God said to him, Go not up after them; turn round them and come upon them opposite the mulberry-trees.

And it shall be, when thou hearest the sound of marching in the tops of the mulberry-trees, that then thou shalt go out to battle; for God will have gone forth before thee to smite the army of the Philistines.

And over the olive trees and mulberry trees that were in the valleys was Baalhanan the Gederite. And over the treasure of oil was Joash.
