[3] The LORD thy God, he will go over before thee, and he will destroy these nations from before thee, and thou shalt possess them: and Joshua, he shall go over before thee, as the LORD hath said. [4] And the LORD shall do to Sihon and to Og, kings of the Amorites, and unto the land of them, whom he destroyed. [5] And the LORD shall give them up before your face, that ye may do unto them according unto all the commandments which I have commanded you. [6] Be strong and of a good courage, fear not, nor be afraid of them: for the LORD thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.
