Keil & Delitzsch

The character of the ungodly family of Cainites was now fully developed in Lamech and his children. The history, therefore, turns from them, to indicate briefly the origin of the godly race. After Abel's death a third son was born to Adam, to whom his mother gave the name of Seth (שׁת, from שׁית, a present participle, the appointed one, the compensation); "for," she said, "God hath appointed me another seed (descendant) for Abel, because Cain slew him." The words "because Cain slew him" are not to be regarded as an explanatory supplement, but as the words of Eve; and כּי by virtue of the previous תּחת is to be understood in the sense of כּי תּחת. What Cain (human wickedness) took from her, that has Elohim (divine omnipotence) restored. Because of this antithesis she calls the giver Elohim instead of Jehovah, and not because her hopes had been sadly depressed by her painful experience in connection with the first-born. Gen 4:26 "To Seth, to him also (הוּא גּם, intensive, vid., Ges. 121, 3) there was born a son, and he called his name Enosh." אנושׁ, from אנשׁ to be weak, faint, frail, designates man from his frail and mortal condition (Psa 8:4; Psa 90:3; Psa 103:15, etc.). In this name, therefore, the feeling and knowledge of human weakness and frailty were expressed (the opposite of the pride and arrogance displayed by the Canaanitish family); and this feeling led to God, to that invocation of the name of Jehovah which commenced under Enos. יהוה בּשׁם קרא, literally to call in (or by) the name of Jehovah, is used for a solemn calling of the name of God. When applied to men, it denotes invocation (here and Gen 12:8; Gen 13:4, etc.); to God, calling out or proclaiming His name (Exo 33:19; Exo 34:5). The name of God signifies in general "the whole nature of God, by which He attests His personal presence in the relation into which He has entered with man, the divine self-manifestation, or the whole of that revealed side of the divine nature, which is turned towards man" (Oehler). We have here an account of the commencement of that worship of God which consists in prayer, praise, and thanksgiving, or in the acknowledgment and celebration of the mercy and help of Jehovah. While the family of Cainites, by the erection of a city, and the invention and development of worldly arts and business, were laying the foundation for the kingdom of this world; the family of the Sethites began, by united invocation of the name of God of grace, to found and to erect the kingdom of God.
