'Tests' in the Bible

The refining pot is for silver, and the furnace for gold, but Yahweh tests the hearts.

I said in my heart, "As for the sons of men, God tests them, so that they may see that they themselves are like animals.

But, Yahweh of Armies, who judges righteously, who tests the heart and the mind, I shall see your vengeance on them; for to you have I revealed my cause.

But, Yahweh of Armies, who tests the righteous, who sees the heart and the mind, let me see your vengeance on them; for to you have I revealed my cause.

But even as we have been approved by God to be entrusted with the Good News, so we speak; not as pleasing men, but God, who tests our hearts.
