a forest: a wild stretch of land thick with trees, and the trees that grow there
In the Bible a forest is untamed country. It is where you go to fell timber, where wild animals roam, and where armies can get lost or trapped. Unlike a planted orchard or a tended vineyard, a forest grows on its own, dense and uncleared, often on the hill country that no one had yet farmed.
Because a forest is so plainly a mass of standing trees, the prophets reach for it again and again as a picture. A proud army or a great nation is a forest, and God's judgment is the fire or the axe that levels it: when the trees come crashing down, so do the people. The same image runs the other way too. A forest is the lair of the lion and the wild beast, so to send a people into the forest, or to leave them at the mercy of what lives there, is to picture danger and ruin.
The word also names the trees as material. Cedar cut from the forest of Lebanon built Solomon's palace, which was itself nicknamed the House of the Forest. The same standing timber, carved and overlaid, becomes the wooden idol the prophets mock.
