Deuteronomy 31:21-23

Young's Literal Translation

²¹ `And it hath been, when many evils and distresses do meet it, that this song hath testified to its face for a witness; for it is not forgotten out of the mouth of its seed, for I have known its imagining which it is doing to-day, before I bring them in unto the land of which I have sworn.'

²² And Moses writeth this song on that day, and doth teach it the sons of Israel,

²³ and He commandeth Joshua son of Nun, and saith, `Be strong and courageous, for thou dost bring in the sons of Israel unto the land which I have sworn to them, and I -- I am with thee.'
