Deuteronomy 31:19
Brenton's English Septuagint · Berean Standard Bible
And now write the words of this song, and teach it to the children of Israel, and ye shall put it into their mouth, that this song may witness for me among the children of Israel to their face.
Now therefore, write down for yourselves this song and teach it to the Israelites; have them recite it, so that it may be a witness for Me against them.
