Ps 24:18

“"See my humility and my travail" [Psalm 25:18]. See my humility, whereby I never, in the boast of righteousness, break off from unity; and my travail, wherein I bear with the unruly ones that are mingled with me. "And forgive all my sins." And, propitiated by these sacrifices, forgive all my sins, not those only of youth and my ignorance before I believed, but those also which, living now by faith, I commit through infirmity, or the darkness of this life.”

“The punishment assumed interiorly, however, is the humility of spirit before God; hence he says, "See," that is, consider, "my humility": Lk. 1: "He has regarded the humility of his handmaid." Likewise, there is also humility manifest exteriorly, which is a certain labor; hence he says, "and my toil": Ps. 72: "They are not in the labor of men," etc. Of good men it is said, Wis. 3: "Glorious is the fruit of good labors." Concerning guilt he says, "Forgive all my sins." Sir. 28: "Sins will be loosed for the one who prays." And note that through three things one obtains the forgiveness of sins: namely through tribulations, which work the forgiveness of sins if they are patiently borne: Tob. 3: "In the time of tribulation you forgive sins, and after the storm you make calm, and after weeping and tears you pour in rejoicing." Likewise through humility: 1 Kgs. 21: "Because Ahab humbled himself before me, I will not bring evil in his days": Ps. 50: "A contrite and humbled heart," etc. Likewise through labor: Deut. 26: "He looked upon our humility and our labor and distresses, and brought us out of Egypt with a mighty hand." And therefore he says, "Forgive all my sins."”
