Witness for me

1. Deut. 31: 19
     19 Now therefore ^awrite ye this ^bsong for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.
2. Mosiah 24: 14
     14 And I will also ease the ^aburdens which are put upon your shoulders, that even you cannot feel them upon your backs, even while you are in bondage; and this will I do that ye may stand as ^bwitnesses for me hereafter, and that ye may know of a surety that I, the Lord God, do visit my people in their ^cafflictions.
