'Strengthen' in the Bible

Jehovah said, Verily I will strengthen thee for good; verily I will cause the enemy to make supplication unto thee in the time of evil and in the time of affliction.

In the prophets of Jerusalem also I have seen a horrible thing: they commit adultery, and walk in lies; and they strengthen the hands of evil-doers, so that none doth return from his wickedness: they are all of them become unto me as Sodom, and the inhabitants thereof as Gomorrah.
