'Faint hearted' in the Bible

He will say to them, "Listen, Israel! You're about to go into battle today against your enemies. Don't be faint-hearted. Don't be afraid, don't panic, and don't be terrified to face them.

"Let the officials also speak to the army, "Is there a man here who is afraid and faint-hearted? Let him go back home. Otherwise, he may demoralize his fellow soldier.'
