The names of Adam’s descendants may have specific meanings, but those meanings aren’t clear. Seth probably means, “a substitute” given by what Eve said in Genesis 4:25 when he was born and from Easton, M. G. (1893). In Easton’s Bible dictionary. New York: Harper & Brothers. The meaning of the names of Seth’s descendants, though, have a variety of options. Enosh (or Enos) might mean “man” according to this commentary, or “mortal, decaying man,” and “man, sickly” according to this one with the same idea presented here. Meanwhile, according to this commentary, Cainan (or Kenan), means “child,” “one begotten,” “a created thing,” “a creature,” “a young man,” “possessor,” or “spearsman.” Cainan might also mean “possession” or “smith” according to Easton, M. G. (1893). In Easton’s Bible dictionary. New York: Harper & Brothers. or even “worker in metal” as stated by Horn, S. H. (1979). In The Seventh-day Adventist Bible Dictionary (p. 172). Review and Herald Publishing Association. Next, Mahalaleel (or Mahalalel) means, “praise of God” or “glory to God” (see here and Horn, S. H. (1979). In The Seventh-day Adventist Bible Dictionary (p. 696). Review and Herald Publishing Association.), while Jared means “a going down, or “the going down, or descending, river” (see here). “Jared” is translated as “descent,” in Easton, M. G. (1893). In Easton’s Bible dictionary. New York: Harper & Brothers and “servant” in Horn, S. H. (1979). In The Seventh-day Adventist Bible Dictionary (p. 552). Review and Herald Publishing Association. Even more options are suggested for Jared here. With the origin of human history so close to when these men lived, as with the names “Cain” and “Abel,” we don’t know if name or the meaning of the name came first, and even figuring out the meaning is pretty tricky. One interesting idea is that the names or details have a form of story embedded in them. In that version, Seth means “put in the place”, Enosh is associated with the calling of the Lord, Cainan (Kenan) may be a reference to Cain and hope in reforming past failures, Mahalalel means “praising God,” and Jared means something like “May God come down.” For this idea, see Doukhan, J. B. (2016). Seventh-day Adventist International Bible Commentary (p. 131). Pacific Press Publishing Association.
