This man was the first that brake the first institution of God concerning marriage. "He took unto him two wives." The New Testament says, Let every man have his own wife. And so said the law in its first institution: therefore plurality of wives first came into practice by the seed of cursed Cain, and for a time was suffered in the world through the hardness of man's heart.
Ver. 20, 21. "And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle. And his brother's name was Jubal: he was the father of all such as handle the harp and organ."
Jabal signifies bringing, or budding; Jubal, bringing or fading. So then in these two sons might be shewed unto us the world, as it is in its utmost glory: that is, it brings buds, it brings fading: today in the field, tomorrow in the oven: "All flesh is grass, and all the goodliness thereof, is as the flower of the field. The grass withereth, the flower fadeth: because the Spirit of the Lord bloweth upon it: surely the people is grass" (Isa 40:6-8).
And observe in these, the last was the musical one. Indeed, the spirit of the world, after things have budded, is so far off from remembering that they again must fade; that then it begins its Requiem; then it saith to itself, Eat, drink, and be merry; then it is for handling the harp and organ (Luke 12:16-20).
Ver. 22. "And Zillah, she also bare Tubal-Cain, an instructor of every artificer in brass and iron: and the sister of Tubal-Cain was Naamah."
Tubal-Cain, a worldly possession; and Naamah, one that by her name should be beautiful. Lamech his fruit then was, a budding, fading, worldly possession, with a little deceitful, vain beauty, for "favour is deceitful, and beauty is vain: but a woman that feareth the Lord, she shall be praised" (Pro 31:30). Ver. 23. "And Lamech said unto his wives, Adah and Zillah, hear my voice; ye wives of Lamech, hearken unto my speech: for I have slain a man to my wounding, and a young man to my hurt."
He that sticks not to exceed in one point, will not fear to transgress in another. He had hardened his heart, by breaking the modest and orderly bounds of marriage, and so fitted himself to shed blood, or do any other wickedness.
"Hearken to me, ye wives." Lustful men break their minds to their fleshly companions, sometimes, sooner than to wiser counsellors. Even as Ahab, in the business of the vineyard of Naboth, breaks his mind to that ungodly Jezebel his wife.
"I have slain a man to my wounding." Who, or what man this murdered person was, therein the word is silent: yet this Lamech being the son of a bloody murderer, it is possible he was some godly man, one of Adam's other children, or of his grandchildren, the son of Seth: for these sons of Cain, and namely this in special, as it seems, took not heed to the mark wherewith God branded Cain; but like Belshazzar, he hardened his heart, though he knew it, and would turn murderer also (Dan 5:18-22).
"I have slain a man to my wounding." The guilt of blood who can bear? or who can help himself thereby? It is a wounding thing, it is a hurtful thing, he that sheds man's blood wrongfully, cannot establish himself thereby (Matt 22:6,7). The Jews thought to have preserved themselves and country by killing Jesus Christ; but this so provoked the justice of God, that for this thing's sake he sent the Gentiles upon them to burn up their city; who when they were come, if stories be true, slew of them eleven hundred thousand; and those of them that were taken alive, were sold to who would buy them, Thirty a penny. "Ye shed blood [says God] and shall ye possess the land? Ye stand upon your sword, ye work abomination, and ye defile every one his neighbour's wife: and shall ye possess the land?" (Eze 33:25,26).
