'Be Strong' in the Bible

And the sons of Israel will be subdued in that time, and the sons of Judah will be strong, for they relied upon Jehovah the God of their fathers.

And behold, Amariah the head priest over you for every word of Jehovah; and Zebadiah son of Ishmael the leader to the house of Judah, for every word of the king: and the scribes, the Levites, before you. Be strong and do, and Jehovah will be with the good.

For if thou goest, to be strong for war: God will cause thee to falter before the enemy, for there is power with God to help and to cause to falter.

And he waged war with the king of the sons of Ammon, and he will be strong against them. And the sons of Ammon will give to him in that year a hundred talents of silver, and ten thousand cors of wheat, and barley ten thousand. This the sons of Ammon turned back to him, in the second year, and the third.

Be strong and be firm ye shall not fear and ye shall not be terrified-from the face of the king of Assur, and from before all the multitude which are with him: for with us much more than with him.
