And Israel saw the great work which the LORD did upon the Egyptians, and the people feared the LORD: and they believed in the LORD, and in his servant Moses.
Then sang Moses and the children of Israel this song unto the LORD, and spake, saying, I will sing unto the LORD, for he hath triumphed gloriously: The horse and his rider hath he thrown into the sea.
And those on the rock are they which, when they have heard, receive the word with joy; and these have no root, which for a while believe, and in time of temptation fall away.
