Genesis 5:14

And all the days of Cainan were nine hundred and ten years, and he died. The Arabic writers F15 Elmacinus, apud Hottinger, p. 233. also commend him as a good ruler of his people; and at his death he charged them not to desert the holy mountain, and join themselves with Cain's posterity; and having appointed Mahalaleel, who they say was his eldest son, his successor, he died on the fourth day of the week, and the thirteenth of the month Cheziran, A. M. 1535, and was buried in the double cave, and they mourned for him, according to custom, forty days: according to Bishop Usher it was in A. M. 1235.
