God is jealous and the Lord revengeth - Rather (as the English margin) God “very jealous and avenging is the Lord.” The Name of God, יהוה (YHVH), “He who Is,” the Unchangeable, is thrice repeated, and thrice it is said of Him that He is an Avenger. It shows both the certainty and greatness of the vengeance, and that He who inflicts it, is the All-Holy Trinity, who have a care for the elect. God’s jealousy is twofold. It is an intense love, not bearing imperfections or unfaithfulness in that which It loves, and so chastening it; or not bearing the ill-dealings of those who would injure what It loves, and so destroying them. To Israel He had revealed Himself as “a Exodus 20:5-6 jealous God, visiting iniquity but shewing mercy;” here, as jealous for His people against those who were purely His enemies and the enemies of His people (see Zechariah 1:14), and so His jealousy burns to their destruction, in that there is in them no good to be refined, but only evil to be consumed.
The titles of God rise in awe; first, “intensely jealous” and “an Avenger;” then, “an Avenger and a Lord of wrath;” One who hath it laid up with Him, at His Command, and the more terrible, because it is so; the Master of it, (not, as man, mastered by it; having it, to withhold or to discharge; yet so discharging it, at last, the more irrevocably on the finally impenitent. And this He says at the last, “an Avenger to His adversaries,” (literally, “those who hem and narrow Him in”). The word “avenged” is almost appropriated to God in the Old Testament, as to punishment which He inflicts, or at least causes to be inflicted , whether on individuals Genesis 4:15, Genesis 4:24; 1Sa 24:12; 2 Samuel 4:8; 2 Kings 9:7; Jeremiah 11:20; Jeremiah 15:15; Jeremiah 20:12, or upon a people, (His own Leviticus 26:25; Psalms 99:8; Ezekiel 24:8 or their enemies Deuteronomy 32:41, Deuteronomy 32:43; Psalms 18:48; Isaiah 34:8; Isaiah 35:4; Isaiah 47:3; Isaiah 59:17; Isaiah 61:2; Isaiah 63:4; Micah 5:14; Jeremiah 46:10; Jeremiah 50:15, Jeremiah 50:28; Jeremiah 51:6, Jeremiah 51:11, Jeremiah 51:36; Ezekiel 25:14, Ezekiel 25:17, for their misdeeds. In the main it is a defect . Personal vengeance is mentioned only in characters, directly or indirectly censured, as Samson Judges 15:7; Judges 16:20 or Saul . It is forbidden to man, punished in him, claimed by God as His own inalienable right. “Vengeance is Mine and requital” (Deuteronomy 32:35, compare Psalms 94:1). “Thou shalt not avenge nor keep up against the children of My people” Leviticus 19:18. Yet it is spoken of, not as a mere act of God, but as the expression of His Being. “Shall not My soul be avenged of such a nation as this?” Jeremiah 5:9, Jeremiah 5:29; Jeremiah 9:9.
And a Reserver of wrath for His enemies - The hardened and unbelieving who hate God, and at last, when they had finally rejected God and were rejected by Him, the object of His aversion. It is spoken after the manner of men, yet therefore is the more terrible. There is that in God, to which the passions of man correspond; they are a false imitation of something which in Him is good, a distortion of the true likeness of God, in which God created us and whisk man by sin defaced. : “Pride doth imitate exaltedness: whereas Thou Alone art God exalted over all. Ambition, what seeks it, but honors and glory? Whereas Thou alone art to be honored above all and glorious for evermore. The cruelty of the great would fain be feared; but who is to be feared but God alone, out of whose power what can be wrested or withdrawn, when, or where, or whither, or by whom? The tendernesses of the wanton would fain be counted love: yet is nothing more tender than Thy charity; nor is aught loved more healthfully than that Thy truth, bright and beautiful above all. Curiosity makes semblance of a desire of knowledge; whereas Thou supremely knowest all. Yea, ignorance and foolishness itself is cloaked under the name of simplicity and uninjuriousness: because nothing is found more single than Thee; and what less injurious, since they are his own works which injure the sinner?
Yea, sloth would fain be at rest; but what stable rest beside the Lord? Luxury affects to be called plenty and abundance; but Thou art the fullness and never-failing plenteousness of incorruptible pleasures. Prodigality presents a shadow of liberality: but Thou art the most overflowing Giver of all good. Covetousness would possess many things; and Thou possessest all things. Envy disputes for excellency: what more excellent than Thou? Anger seeks revenge: who revenges more justly than Thou? Fear startles at things unaccustomed or sudden, which endanger things beloved, and takes forethought for their safety; but to Thee what unaccustomed or sudden, or who separats from Thee what Thou lovest? Or where but with Thee is unshaken safety? Grief pines away for things lost, the delight of its desires; because it would have nothing taken from it, as nothing can from Thee. Thus doth the soul seek without Thee what she finds not pure and untainted, until she returns to Thee. Thus, all pervertedly imitate Thee, who remove far from Thee, and lift themselves up against Thee. But even by thus imitating Thee, they imply Thee to be the Creator of all nature; whence there is no place, whither altogether to retire from Thee.” And so, in man, the same qualities are good or bad, as they have God or self for their end. : “The joy of the world is a passion. Joy in the Holy Spirit or to joy in the Lord is a virtue. The sorrow of the world is a passion. The sorrow according to God which works salvation is a virtue. The fear of the world which hath torment, from which a man is called fearful, is a passion. The holy tear of the Lord, which abides forever, from which a man is called reverential, is a virtue. The hope of the world, when one’s hope is in the world or the princes of the world, is a passion. Hope in God is a virtue, as well as faith and charity. Though these four human passions are not in God, there are four virtues, having the same names, which no one can have, save from God, from the Spirit of God.” in man they are “passions,” because man is so far “passive” and suffers under them, and, through original sin, cannot hinder having them, though by God’s grace he may hold them in.
God, without passion and in perfect holiness, has qualities, which in man were jealousy, wrath, vengeance, unforgivingness, a “rigor of perfect justice toward the impenitent, which punishes so severely, as though God had fury;” only, in Him it is righteous to punish man’s unrighteousness. Elsewhere it is said, “God keepeth not for ever” Psalms 103:9, or it is asked, “will He keep forever?” Jeremiah 3:5, and He answers, “Return, and I will not cause Mine anger to fall upon you, for I am merciful, saith the Lord, I will not keep for ever” Jeremiah 3:12. Man’s misdeeds and God’s displeasure remain with God, to be effaced on man’s repentance, or “by his hardness and impenitent heart man treasureth up unto himself wrath in the day of wrath and of the revelation of the righteous judgment of God, who will reward each according to his works” Romans 2:5-6.
