The weapon of discouragement

2 Chronicles 32:6-8 (NKJV)

⁶ Then he set military captains over the people, gathered them together to him in the open square of the city gate, and gave them encouragement, saying, ⁷ “Be strong and courageous; do not be afraid nor dismayed before the king of Assyria, nor before all the multitude that is with him; for there are more with us than with him. ⁸ With him is an arm of flesh; but with us is the Lord our God, to help us and to fight our battles.” And the people were strengthened by the words of Hezekiah king of Judah.
