As he loved cursing, {i} so let it come unto him: as he delighted not in blessing, so let it be far from him.

(i) Thus the Lord gives to every man the thing in which he delights so that the reprobate cannot accuse God of wrong, when they are given up to their lusts and reprobate minds.

Wesley's Notes

109:17 Delighted not - In desiring and promoting the welfare of others.

Jamieson-Fausset-Brown Bible Commentary

17-19. Let his loved sin, cursing, come upon him in punishment (Ps 35:8), thoroughly fill him as water and oil, permeating to every part of his system (compare Nu 5:22-27), and become a garment and a girdle for a perpetual dress.

Matthew Henry's Concise Commentary

109:6-20 The Lord Jesus may speak here as a Judge, denouncing sentence on some of his enemies, to warn others. When men reject the salvation of Christ, even their prayers are numbered among their sins. See what hurries some to shameful deaths, and brings the families and estates of others to ruin; makes them and theirs despicable and hateful, and brings poverty, shame, and misery upon their posterity: it is sin, that mischievous, destructive thing. And what will be the effect of the sentence, Go, ye cursed, upon the bodies and souls of the wicked! How it will affect the senses of the body, and the powers of the soul, with pain, anguish, horror, and despair! Think on these things, sinners, tremble and repent.
