20 When thou goest out to war against thine enemies, and seest horses, and chariots, [and] a people more numerous than thou, thou shalt not fear them; for Jehovah thy God is with thee, who brought thee up out of the land of Egypt.

² And it shall be, when ye approach unto the battle, that the priest shall draw near and speak unto the people,

³ and shall say unto them, Hear, Israel, ye are approaching this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be afraid of them;
