Proverbs 3:16

Length of days is in her right hand, etc. With the vision of his divinity, He grants the chosen ones in perpetual light, and in this present life, he strengthens and illuminates them with the sacraments and charisms of his incarnation. He gives them, who sell all things for themselves, a hundredfold in this time, and eternal life in the future age. It follows in this place according to the ancient translation, which our codices do not have: Justice proceeds from his mouth, but he carries law and mercy on his tongue. This I believed should be noted because verses are often found placed in the works of the Fathers.

As Proverbs has it, "Length of days and years of life are in his right hand," and this means eternal blessedness, whereas "In his left hand are riches and glory," denoting the good things of this world, though there is no doubt that these can be bestowed by him. Moreover, it is his right side to which the saints are allotted when separated from the rest to obtain their rewards, whereas the left side is that mentioned when sinners are to be condemned to eternal punishment; for the saints have longed for things heavenly, whereas sinners have sought worldly goods. We also read that sinners have given the left hand's role to their right hand; our prophet is to say of them in Psalm 143: "Their mouth has spoken vanity, and their right hand is the right hand of iniquity." But the true use of the right hand is where the bestowal of the Lord's grace is demonstrated.

Someone may object: If the just man has no left hand, how is Wisdom written to have both a right hand and a left? A diligent reader will very easily judge how great is the difference between the right hand of Wisdom and the left, when he has noticed what things are said to be in her right and what in her left. For it is said: "Length of eternity and years of life are in her right hand, but in her left hand riches and glory." You see eternal time and perpetual life placed in Wisdom's right hand; but the carnal things which pass away, which flee off while they are thought to be held—that is, riches and glory—placed in her left hand, according to that, that on the day of judgment some will stand at the right, and others at the left: the lambs, that is, and the saints at his right, but the goats and the sinners at his left.
