me-hu'-ja-el (mechuya'el, mechiya'el, "smitten of God"): A descendant of Cain through Enoch and Irad (Genesis 4:18). The list in Genesis 5:12; is a working-over of the same material of genealogy by another hand at a different date of spelling (compare spelling of Chaucer and that of today). In that ease, Mehalalel would be the correspondent name to Mehujael (see Expository Times, X, 353).
