Deuteronomy — Chapter 20

When thou goest out to battle against thy enemies, and seest horsemen and chariots, and the numbers of the enemy's army greater than thine, thou shalt not fear them: because the Lord thy God is with thee. The laws of holy war: courage in battle comes from trust in God, not in numbers. The priest addresses the host before battle (v. 2), reminding them that God fights for them. Lapide: 'They trust in chariots, and they in horses; but we will call upon the name of the Lord our God' (Ps. 19:8).
