When Israel saw the great power which the Lord used upon the Egyptians, the people feared the Lord, and they believed in the Lord and in His servant Moses.
Then Moses and the Israelites sang this song to the Lord and spoke, saying: “I will sing to the Lord, for He has triumphed gloriously! He has thrown the horse and his rider into the sea!
Those on the rock are the ones who, when they hear the word, receive it with joy. But these have no root, for they believe for a while, then in the time of temptation fall away.
