'Profit' in the Bible

"The priests didn't say, "Where is the LORD?' and those handling the Law didn't know me. The rulers transgressed against me, the prophets prophesied by Baal, and they followed that which does not profit.

Has a nation ever changed gods when they aren't even gods? But my people have exchanged their glory for that which does not profit.

They have sown wheat, but they have harvested thorns. They have tired themselves out, but they don't show a profit. Now be disappointed about your harvest because of the fierce anger of the LORD.

LORD, my strength and my stronghold, my refuge in a time of difficulty, to you the nations will come, and from the ends of the earth they'll say, "Surely our ancestors inherited deception, things that are worthless, and in which there is no profit."
