'Hair' in the Bible

The first son came out reddish his entire body was covered with hair so they named him Esau.

But Jacob replied, "My son isn't going back with you, since his brother is dead and he's the only one left. If something should harm him as you travel, then it'll be death for me and my sad, gray hair!"

If you take this one from me, too, and then something harmful happens to him, then it will be death for me and my sad, gray hair!'

when he notices that the young man hasn't come back with us, he'll die, and your servants really will have brought death to your servant, our father, along with his sad, gray hair!
