And Israel saw the great work which the Lord did against the Egyptians, and the people feared the Lord; and they believed in the Lord and in his servant Moses.
Then Moses and the people of Israel sang this song to the Lord, saying, “I will sing to the Lord, for he has triumphed gloriously; the horse and his rider he has thrown into the sea.
And the ones on the rock are those who, when they hear the word, receive it with joy; but these have no root, they believe for a while and in time of temptation fall away.
