'Testing' in the Bible

But, O Lord of armies, judging in righteousness, testing the thoughts and the heart, let me see your punishment come on them: for I have put my cause before you.

But you, O Lord, have knowledge of me; you see me, searching and testing how my heart is with you: let them be pulled out like sheep to be put to death, make them ready for the day of death.

But, O Lord of armies, testing the upright and seeing the thoughts and the heart, let me see your punishment come on them; for I have put my cause before you.
