'Be Strong' in the Bible

And now you must not scoff, or your bonds will be strong, for I have heard from the Lord, Yahweh of hosts: complete destruction decreed upon all the land.

Say to those who are hasty of heart, "Be strong; you must not fear! Look! your God will come [with] vengeance, [with] {divine retribution}. He {is the one who} will come and save you."
