'Forest' in the Bible

So the people went out into the field against Israel: and the battle was in the forest of Ephraim.

For the battle was there spread over the surface of all the country; and the forest devoured more people that day than the sword devoured.

They took Absalom, and cast him into the great pit in the forest, and raised over him a very great heap of stones. Then all Israel fled everyone to his tent.
