He is your praise, and he is your God, who has done for you these great and awesome things your own eyes have seen.
In context
19So you too must love the foreigner, for you were foreigners in the land of Egypt. 20Fear Yahweh your God, serve him, hold fast to him, and take your oaths in his name. 21He is your praise, and he is your God, who has done for you these great and awesome things your own eyes have seen. 22Your fathers went down to Egypt seventy in number, and now Yahweh your God has made you as numerous as the stars of the sky.
