Genesis 49:3

See the extent of the good man's wisdom. Intending to level a worse accusation against Reuben, he first mentioned the privileges conceded him by nature and the precedence he enjoyed in being the beginning of his line and enjoying the dignity of firstborn. Then he records his sins of free will as if on a bronze pillar to show that no advantage comes to us from natural advantage unless accompanied by good deeds of free will—these, you see, are what bring us commendation or lend us the stigma of blame. "Unyielding in endurance," he says, "unyielding in willfulness": the pride of place accorded you by nature you have forfeited by your own headstrong behavior.

It seems to me that, according to the mystical interpretation, Reuben may play the role of the first Jewish people, that is, the firstborn and the beginning of the children, as the prophet says: "Israel is my firstborn." The words of God in fact were first addressed to that people. And the Scriptures relate that that people was hard and reckless. About whom the prophet says, "Whatsoever this people says, is hard." Elsewhere he says again about the Jews, "You stiff-necked people, uncircumcised in heart." And these people offended God the Father when they turned their back to him and not their face. They defiled the concubine's bed into which they got, that is, the law of the Old Testament, which they often stained with their transgressions. Paul teaches us that the concubine symbolically represents the law of the Old Testament by saying, "Abraham had two sons, one by a slave and one by a free woman: these are the two Testaments"; and Hagar, who was the concubine, clearly is the figure of the Old Testament.One indeed was the perfect dove or mother, the church that, as a chaste virgin and as a queen for her bridegroom the king, is united through the gospel to Christ.

For there was a great display of strength made by God in behalf of His first-born people from Egypt. For in very many ways was the land of the Egyptians chastised. That first people of the circumcision is meant by "my strength, and the first of my children: "even as God gave the promise to Abraham and to his seed. But "hard to bear with," because the people hardened itself against the obedience of God. And "hard, self-willed," because it was not only hard against the obedience of God, but also self-willed so as to set upon the Lord. "Thou hast waxed wanton," because in the instance of our Lord Jesus Christ the people waxed wanton against the Father. But "boil not over," says the Spirit, by way of comfort, that it might not, by boiling utterly over, be spilt abroad,-giving it hope of salvation. For what has boiled over and been spilt is lost.

Reuben thou art my first-born - Jacob here puts upon him the ornaments of the birth-right, that he and all his brethren might see what he had forfeited and in that might see the evil of his sin. As the first-born he was his father's joy, being the beginning of his strength.

How welcome he was to his parents his name bespeaks, Reuben, See a son. To him belonged the excellency of dignity above his brethren, and some power over them. Christ Jesus is the firstborn among many brethren, and to him, of right, belong the most excellent power and dignity: his church also, through him, is a church of firstborn.
