48:1-7 The death-beds of believers, with the prayers and counsels of dying persons, are suited to make serious impressions upon the young, the gay, and the prosperous: we shall do well to take children on such occasions, when it can be done properly. If the Lord please, it is very desirable to bear our dying testimony to his truth, to his faithfulness, and the pleasantness of his ways. And one would wish so to live, as to give energy and weight to our dying exhortations. All true believers are blessed at their death, but all do not depart equally full of spiritual consolations. Jacob adopted Joseph's two sons. Let them not succeed their father, in his power and grandeur in Egypt; but let them succeed in the inheritance of the promise made to Abraham. Thus the aged dying patriarch teaches these young persons to take their lot with the people of God. He appoints each of them to be the head of a tribe. Those are worthy of double honour, who, through God's grace, break through the temptations of worldly wealth and preferment, to embrace religion in disgrace and poverty. Jacob will have Ephraim and Manasseh to know, that it is better to be low, and in the church, than high, and out of it.
4. Behold, I will make thee fruitful—This is a repetition of the covenant (Ge 28:13-15; 35:12). Whether these words are to be viewed in a limited sense, as pointing to the many centuries during which the Jews were occupiers of the Holy Land, or whether the words bear a wider meaning and intimate that the scattered tribes of Israel are to be reinstated in the land of promise, as their "everlasting possession," are points that have not yet been satisfactorily determined.
