He is thy praise,.... The object and matter of it, who deserves the praises of all his creatures, because of his perfections, works, and blessings of goodness; for all mercies temporal and spiritual come from him, and therefore he is greatly to be praised for them: praise is his due, and it is comely in his people to give it to him; see Jer 17:14. and he is thy God which hath done for thee these great and terrible things which thine eyes have seen; which were done upon the Egyptians for their sakes, both in the land of Egypt and at the Red sea; and also what he had done for them in the wilderness, to Sihon and Og, kings of the Amorites, Psa 106:22.
