The son of Jared in the KJV is called Enoch. This is a very interesting transliteration. I would suggest a very poor transliteration. The Hebrew name here is Chanok. This word is from the root chanak (חנך), and means to train, teach or dedicate to establish a habit. This same word is where we get the festival of Chanukkah. It is also found in the oft quoted Proverb:

Mishlei (Proverbs) 22:6Train up [chanak] a child in the way he should go: and when he is old, he will not depart from it.

The next word is Methuselah.

Shalom Alecheim!
