Deuteronomy 31:1-6 ASV

1 And Moses went and spake these words unto all Israel.
2 And he said unto them, I am a hundred and twenty years old this day; I can no more go out and come in: and Jehovah hath said unto me, Thou shalt not go over this Jordan.
3 Jehovah thy God, he will go over before thee; he will destroy these nations from before thee, and thou shalt dispossess them: [and] Joshua, he shall go over before thee, as Jehovah hath spoken.
4 And Jehovah will do unto them as he did to Sihon and to Og, the kings of the Amorites, and unto their land; whom he destroyed.
5 And Jehovah will deliver them up before you, and ye shall do unto them according unto all the commandment which I have commanded you.
6 Be strong and of good courage, fear not, nor be affrighted at them: for Jehovah thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.
