(Exodus 15:1) "For He is high on high": He exalted me, and I exalted Him. He exalted me in Egypt, viz. (Exodus 4:22) "My first-born son is Israel," and I exalted Him in Egypt, viz. (Isaiah 20:29) "The song will be for you, as on the night of the sanctification of the festival (of Pesach), and rejoicing of heart as one going with flute to come to the mountain of the L–rd, to the Rock of Israel."
