I. His marrying two wives. It was one of the degenerate race of Cain who first transgressed that original law of marriage that two only should be one flesh. Hitherto one man had but one wife at a time; but Lamech took two. From the beginning it was not so. Malachi 2:15, 19:5. See here, 1. Those who desert God’s church and ordinances lay themselves open to all manner of temptation. 2. When a bad custom is begun by bad men sometimes men of better characters are, through unwariness, drawn in to follow them. Jacob, David, and many others, who were otherwise good men, were afterwards ensnared in this sin which Lamech begun.MHBCC 5.39

II. His happiness in his children, notwithstanding this. Though he sinned, in marrying two wives, yet he was blessed with children by both, and those such as lived to be famous in their generation, not for their piety, no mention is made of this (for aught that appears they were the heathen of that age), but for their ingenuity. They were not only themselves men of business, but men that were serviceable to the world, and eminent for the invention, or at least the improvement, of some useful arts. 1. Jabal was a famous shepherd; he delighted much in keeping cattle himself, and was so happy in devising methods of doing it to the best advantage, and instructing others in them, that the shepherds of those times, nay, the shepherds of after-times, called him father; or perhaps, his children after him being brought up to the same employment, the family was a family of shepherds. 2. Jubal wa 33ae s a famous musician, and particularly an organist, and the first that gave rules for the noble art or science of music. When Jabal had set them in a way to be rich, Jubal put them in a way to be merry. Those that spend their days in wealth will not be without the timbrel and harp, Job 21:12, 21:13. From his name, Jubal,probably the jubilee-trumpet was so called; for the best music was that which proclaimed liberty and redemption. Jabal was their Pan and Jubal their Apollo. 3. Tubal Cain was a famous smith, who greatly improved the art of working in brass and iron, for the service both of war and husbandry. He was their Vulcan. See here, (1.) That worldly things are the only things that carnal wicked people set their hearts upon and are most ingenious and industrious about. So it was with this impious race of cursed Cain. Here were a father of shepherds and a father of musicians, but not a father of the faithful. Here was one to teach in brass and iron, but none to teach the good knowledge of the Lord. Here were devices how to be rich, and how to be mighty, and how to be merry, but nothing of God, nor of his fear and service, among them. Present things fill the heads of most people. (2.) That even those who are destitute of the knowledge and grace of God may be endued with many excellent and useful accomplishments, which may make them famous and serviceable in their generation. Common gifts are given to bad men, while God chooses to himself the foolish things of the world.MHBCC 5.40
