'Trees' in the Bible

So David again asked God what he should do. This time God told him, "Don't march up after them; circle around them and come against them in front of the trees.

When you hear the sound of marching in the tops of the trees, then attack. For at that moment the Lord is going before you to strike down the army of the Philistines."

Then let the trees of the forest shout with joy before the Lord, for he comes to judge the earth!

Baal-Hanan the Gederite was in charge of the olive and sycamore trees in the lowlands; Joash was in charge of the storehouses of olive oil.
