'Mulberry' in the Bible

When David inquired of Yahweh, he said, "You shall not go up. Circle around behind them, and attack them over against the mulberry trees.

It shall be, when you hear the sound of marching in the tops of the mulberry trees, that then you shall stir yourself up; for then Yahweh has gone out before you to strike the army of the Philistines."

David inquired again of God; and God said to him, "You shall not go up after them. Turn away from them, and come on them over against the mulberry trees.

It shall be, when you hear the sound of marching in the tops of the mulberry trees, that then you shall go out to battle; for God has gone out before you to strike the army of the Philistines."
