Charles Ellicott Commentary Genesis 5:18

"And Jared lived a hundred sixty and two years, and begat Enoch:" — Genesis 5:18 (ASV)

Jared. —Hebrew, Yered. This name is supposed to mean the descent, especially of water. Therefore, many have endeavored to show that he is the Indian water-god Varuna; but competent modern commentators regard all such Aryan expositions as refuted. Mr. Sayce tells us that the word in Assyrian means servant (Chaldean Genesis, page 311), but this is not quite satisfactory. Until, however, this very ancient Semitic dialect is thoroughly explored, we are scarcely in a position to speak with certainty about these old names.

Further, he was 162 years of age when he fathered Enoch. It is probable from this that Enoch was not the eldest son, but that the birthright became his because of his special excellencies. It is also to be observed that Enoch holds the seventh place from Adam, seven being the number of perfection; that he attains the highest rank among the patriarchs; and that he passes into immortality without death.
