The son of Japheth. (Genesis 10:2) His name is probably taken from Thebal, earth. And there was a Tubal-Cain, son of Lamech. It. hath been thought by some that as Cain is derived from Canah, this junction seems to imply that this man had much earthly possession, or perhaps figuratively so called from being the first instructor, or as the margin of the Bible renders it, the whetter of the metals of the earth. (See Genesis 4:22)
