Deuteronomy 31:19-26

ASV_Strongs(i)
  19 H3789 Now therefore write H7892 ye this song H3925 for you, and teach H1121 thou it the children H3478 of Israel: H7760 put H6310 it in their mouths, H7892 that this song H5707 may be a witness H1121 for me against the children H3478 of Israel.
  20 H935 For when I shall have brought H127 them into the land H7650 which I sware H1 unto their fathers, H2100 flowing H2461 with milk H1706 and honey, H398 and they shall have eaten H7646 and filled H1878 themselves, and waxed fat; H6437 then will they turn H312 unto other H430 gods, H5647 and serve H5006 them, and despise H6565 me, and break H1285 my covenant.
  21 H7227 And it shall come to pass, when many H7451 evils H6869 and troubles H4672 are come upon H7892 them, that this song H6030 shall testify H6440 before H5707 them as a witness; H7911 for it shall not be forgotten H6310 out of the mouths H2233 of their seed: H3045 for I know H3336 their imagination H6213 which they frame H3117 this day, H935 before I have brought H776 them into the land H7650 which I sware.
  22 H4872 So Moses H3789 wrote H7892 this song H3117 the same day, H3925 and taught H1121 it the children H3478 of Israel.
  23 H3091 And he gave Joshua H1121 the son H5126 of Nun H6680 a charge, H559 and said, H2388 Be strong H553 and of good courage; H935 for thou shalt bring H1121 the children H3478 of Israel H776 into the land H7650 which I sware unto them: and I will be with thee.
  24 H4872 And it came to pass, when Moses H3615 had made an end H3789 of writing H1697 the words H8451 of this law H5612 in a book, H8552 until they were finished,
  25 H4872 that Moses H6680 commanded H3881 the Levites, H5375 that bare H727 the ark H1285 of the covenant H3068 of Jehovah, H559 saying,
  26 H3947 Take H5612 this book H8451 of the law, H7760 and put H6654 it by the side H727 of the ark H1285 of the covenant H3068 of Jehovah H430 your God, H5707 that it may be there for a witness against thee.
