81:5 This he ordained in {d} Joseph [for] a testimony, when he went out through the land of Egypt: [where] I heard a language [that] {e} I understood not.
(d) That is, in Israel for Joseph's family was counted the chief while before, Judah was preferred.
(e) God speaks in the person of the people because he was their leader.
81:5 Joseph - Among the people of Israel. Testimony - For a witness of that glorious deliverance. He - God. Went - As a captain at the head of his people. Egypt - To execute his judgments upon that land. I - My progenitors, for all the successive generations of Israel make one body, and are sometimes spoken of as one person. A language - The Egyptian language, which at first was unknown to the Israelites, Gen 42:13, and probably continued so for some considerable time, because they were much separated both in place and conversation from the Egyptians.
81:1-7 All the worship we can render to the Lord is beneath his excellences, and our obligations to him, especially in our redemption from sin and wrath. What God had done on Israel's behalf, was kept in remembrance by public solemnities. To make a deliverance appear more gracious, more glorious, it is good to observe all that makes the trouble we are delivered from appear more grievous. We ought never to forget the base and ruinous drudgery to which Satan, our oppressor, brought us. But when, in distress of conscience, we are led to cry for deliverance, the Lord answers our prayers, and sets us at liberty. Convictions of sin, and trials by affliction, prove his regard to his people. If the Jews, on their solemn feast-days, were thus to call to mind their redemption out of Egypt, much more ought we, on the Christian sabbath, to call to mind a more glorious redemption, wrought out for us by our Lord Jesus Christ, from worse bondage.
