Praise God from the earth and so forth. Isaiah said (Isaiah 43:7), "everyone who is called by My name, and so forth." The Lord did not create man except for His glory. As it is said (Proverbs 16:4), "The Lord has made everything for its own purpose, and so forth."
He created them to praise Him. As it is said (Psalms 19:2), "The heavens declare the glory of God, and so forth." Just as the heavens and all that is in them praise Him, so too does the earth and all that is in it praise Him. As it is said, "Praise God from the earth."
Everyone praises the King. And who praises Him first? The sons of the palace, and afterwards the sons of the province. Therefore, it is said, "Praise God from the heavens, and so forth."
After they praised Him in the heavens. And who praises Him first? One who is greater than his companion. And who are these great ones?
The sea monsters. As it is said (Genesis 1:21), "God created the great sea monsters." Therefore, they praise Him first. As it is said, "Sea monsters and all depths."
And how many depths are there that have not been explored? As it is said (Proverbs 8:24), "When there were no depths I was brought forth." And it is written (Exodus 15:5), "The depths covered them." And until now, no one knows how many there are.
Until the sons of Korah said (Psalms 42:8), "Deep calls to deep, and so forth." Therefore, it is said, "Sea monsters and all depths." Let all praise the name of God.
