Then said the LORD unto Moses, Behold, I will rain bread from heaven for you; and the people shall go out and gather a certain portion every day, that I may prove them, whether they will walk in my law, or not.

And Moses said unto the people, Fear not: for God has come to prove you, and that his fear may be before your faces, that you sin not.

And these were they who went up from Tel-melah, Tel-harhsa, Cherub, Addan, and Immer: but they could not prove their father's house, and their descent, whether they were of Israel:

And these were they who went up also from Tel-melah, Tel-harsha, Cherub, Addon, and Immer: but they could not prove their father's house, nor their descendants, whether they were of Israel.

If I justify myself, my own mouth shall condemn me: if I say, I am blameless, it shall also prove me perverse.

Examine me, O LORD, and prove me; try my heart and my mind.
