He smote the first-born of Egypt He now reverts to those more special benefits, by which God had laid his Church and chosen people under obligation to his service. As it was the Lord's believing people only whom he addressed, the chief point singled out as the subject of praise is God's having adopted them, small as they were in numbers, from the mass of the human family. Again, there was the fact of his having set himself in opposition, for their sakes, to great kingdoms and mighty nations. The wonderful works done by God in Egypt and in Canaan were all just so many proofs of that fatherly love which he entertained for them as his chosen people. It is not strictly according to historic order to begin with mentioning the destruction of the first-born of Egypt; but this is instanced as a memorable illustration of the great regard God had for the safety of his people, which was such that he would not spare even so mighty and wealthy a nation. The scope of the passage is to show that God, in delivering his people, had abundantly testified his power and his mercy.

Who smote the firstborn of Egypt - As the last and the greatest of the plagues brought upon the Egyptians; the chief and crowning judgment under which they were made willing that the children of Israel should go, and which was in fact the judgment which secured their freedom. This is selected here evidently for this reason, instead of recounting all the plagues which were brought upon the Egyptians.
Both of man and beast - Exodus 11:5. Margin, as in Hebrew, From man unto beast. That is, including both; smiting both.

Who smote the first-born of Egypt - See the parallel passages.

Who smote the firstborn of Egypt, both of man and beast. Which was the last of the plagues inflicted on the Egyptians; and is particularly mentioned, because, by means of it, they were made willing to let the children of Israel go out of their land: and so this includes the deliverance of the Israelites, God's firstborn, when he slew the firstborn of Egypt; and who were typical of the firstborn, whose names are written in heaven; and the deliverance of them, through the blood of the passover, was an emblem of the deliverance of those by the blood of Christ; see Exodus 12:22.

The last plague [Exodus 12:29] is cited to illustrate His "tokens and wonders."

Worthy is He to be praised, for He is the Redeemer out of Egypt. בּתוככי as in Psalm 116:19, cf. Psalm 105:27.
