Chapter I.
In order to encourage children to show honor to their parents, God bestowed great power upon the blessing of parents. Joseph hastened to receive his father's blessing and also offered his sons to be blessed. And these mysteries are contained in them.
First of all, let us show great reverence to our parents, as we read in Genesis 9:25-27, that whoever was blessed by their father, was blessed, and whoever was cursed by their father, was cursed! Therefore, God has granted this grace to parents, so that the piety of their children may be provoked. Therefore, it is the duty of children to obey their parents. Honor your father, so that he may bless you. Let the dutiful honor their father out of gratitude, the ungrateful out of fear. And even if the father is poor, and does not have riches to leave to his children; he still has the inheritance of ultimate blessing, which he can bestow on his successors as the wealth of sanctification. And it is much more blessed to become rich.
Joseph was eager to receive the blessing (Gen. XLVIII, 1 et seq.). Finally, he presented his sons Manasseh and Ephraim, whom Jacob blessed. And because he had twelve sons, and the thirteenth was to be the apostle Paul, as if a later chosen one, the thirteenth Tribes of Manasseh and Ephraim were sanctified in both, so that Paul would not be found outside the number of the paternal Tribes, who was an outstanding preacher of the Old and New Testament and could easily prove his inheritance of the paternal blessing.
Although these mysteries are glorious in this, that Joseph, taking his sons whom he had adopted in Egypt, Ephraim, he placed at his right hand, but Manasseh at his left, so that Israel, their father, was on their right side. But Israel stretched out his right hand and laid it upon the head of Ephraim, who was the younger and stood at his left side; and his left hand he laid upon Manasseh, who was at his right side. And thus, changing his hands, he blessed them. In this, Joseph also preserved the order of nature by giving more deference to his elder son, just as Isaac also desired to give the blessing to his firstborn son, Esau. But he believed that the younger son should be preferred in the role of the younger people, just as he himself was preferred by his mother.
Finally, Manasses is designated by the Latin interpretation as coming from oblivion (Gen. XLI, 51), because the people of Judah forgot their God who made them. And whoever from that people believes, is called back from oblivion. Ephraem, however, promises the abundance of faith by the interpretation of his name, who increased his father, as Joseph himself says: Because God increased me in the land of my humility (Ibid., 52). This is the characteristic of the younger people, who is the body of Christ, increasing the Father and not abandoning their own God.
Finally, the Lord, speaking in a spiritual manner about the people, declared this to be a mystery. For when the son thought his father had made a mistake due to his dull appearance, he wanted to turn his hands around, saying, 'Not so, Father, for this one is the firstborn; place your right hand on his head.' But his father refused and said, 'I know, my son, I know. He will also become a people, and he will be exalted. However, his younger brother will be greater than he, and his descendants will become a multitude of nations.' (Genesis 48:18-19). Finally, he preferred the elder Ephraem, even prophesying in a series of blessings, saying: 'In you Israel shall be blessed, saying: May God make you like Ephraem and Manasseh' (Ibid., 20). And therefore, since they were grandsons, they were adopted in place of sons, so that they would not be deprived of the ancestral blessing.
