It is probable, that Israel, upheld by the arm of JEHOVAH, accomplished some mighty acts here. But the record of them is not come down to us. See Exodus 17:14. But some have thought, and not without reason, that as the Red Sea is mentioned here, the children of Israel, in the view of the brooks of Arnon, were prompted to sing again the song of triumph, which they had sung near forty years before at the Red Sea. Exodus 15:1, etc. Reader, it is sweet at every renewed instance of mercy, we meet with in our pilgrimage, to look back and rehearse the righteous acts of the LORD. You and I shall find enough, like Jacob, to sing of in the recollection of every stage we have come. The GOD which fed me all my life long unto this day; the angel (JESUS) which redeemed me from all evil. Genesis 48:15-16.
