'Be Strong' in the Bible

And now ye shall not be mocker's lest your bonds shall be strong: for I heard a completion and decision from the Lord. Jehovah of armies upon all the earth.

Say to those hasty of heart, Be strong ye shall not fear; behold, your God will come with vengeance, the recompense of God; he will come and save you.

They will help a man his neighbor, and he will say to his brother, Be strong.

Jehovah as a strong one shall go forth; as a man of war he shall raise up jealousy: he shall shout, also he shall cry aloud; he shall be strong against his enemies.
