'Belong' in the Bible

The LORD's eyes keep on roaming throughout the earth, looking for those whose hearts completely belong to him, so that he may strongly support them. But because you have acted foolishly in this, from now on you will have wars."

"Pay attention, everyone in Judah, in Jerusalem, and you, too, King Jehoshaphat! This is what the LORD says to you: "Stop being afraid, and stop being discouraged because of this vast invasion force, because the battle doesn't belong to you, but to God.
