3 Then, in what next follows, Christ speaks, as it were, in His own person: “Then I restored that,” says He, “which I took not away;”that is, on account of the sin of Adam I endured the death which was not mine by sinning. “For, O God, You know my foolishness; and my sins are not hid from You,” that is, “for I did not sin,” as He means it; and for this reason (it is added), “Let not them be ashamed who want to see” my resurrection on the third day, to wit, the apostles.
“Because for Your sake,” that is, for the sake of obeying You, “I have borne reproach,” namely the cross, when “they covered my face with shame,” that is to say, the Jews; when “I became a stranger unto my brethren after the flesh, and an alien unto my mother's children,” meaning (by the mother) the synagogue. “For the zeal of Your house, Father, has eaten me up; and the reproaches of them that reproached You are fallen on me,” and of them that sacrificed to idols. Wherefore “they that sit in the gate spoke against me,” for they crucified me without the gate.
“And they that drink sang against me,” that is, (they who drink wine) at the feast of the passover. “But as for me, in my prayer unto You, O Lord, I said, Father, forgive them,” namely the Gentiles, because it is the time for favour with Gentiles. “Let not then the hurricane (of temptations) overwhelm me, neither let the deep (that is, Hades) swallow me up: for You will not leave my soul in hell (Hades); neither let the pit shut her mouth upon me,” that is, the sepulchre. “By reason of mine enemies, deliver me,” that the Jews may not boast, saying, Let us consume him.
