'Strengthen' in the Bible

Yahweh said, Most certainly I will strengthen you for good; most certainly I will cause the enemy to make supplication to you 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 evildoers, so that none does return from his wickedness: they are all of them become to me as Sodom, and its inhabitants as Gomorrah.
