'Song' in the Bible

Then sang Moses and the children of Israel this song to Jehovah, and spoke, saying, I will sing unto Jehovah, for he is highly exalted: The horse and his rider hath he thrown into the sea.

My strength and song is Jah, and he is become my salvation: This is my God, and I will glorify him; My father's God, and I will extol him.
