Numbers 21:35

So they smote him and his sons and all his people, until there was none left him alive; and they possessed his land. Thus Israel, courageous through its confidence in Jehovah, was able to overthrow mighty kings, a fact which is so often referred to in later times, Deuteronomy 3:1; Psalms 135:11; Psalms 136:19. All this Israel wrought through faith, Hebrews 11:33. He that truly believes in the Lord has the strength to conquer all his enemies, and will gladly give thanks to God for His goodness and mercy.
