'Courage' in the Bible

When Saul’s son Ish-bosheth heard that Abner had died in Hebron, his courage failed, and all Israel was dismayed.

since You, Lord of Hosts, God of Israel, have revealed this to Your servant when You said, “I will build a house for you.” Therefore, Your servant has found the courage to pray this prayer to You.

Be of good courage, and let us play the men for our people, and for the cities of our God: and the LORD do that which seemeth him good.

Foreigners lost their courage, coming trembling from their strongholds.
