And the first came out red
Either his body, or rather the hair it was covered with, red; which was a sign, as Jarchi observes, that he would be a shedder of blood, fierce and cruel as were he and his posterity: all over like an hairy garment;
his body was all over full of hair, which stood as thick as a garment made of hair, and was a sign of the roughness of his disposition, as well as of the strength of his body: and they called his name Esau;
his parents, and those present at his birth, all that saw him thus covered with hair; for he had his name not from the colour of his body or hair; for the word does not signify "red", but comes from a word which signifies "to make", he being a "maker": that made his way out before his brother, or an active man as afterwards, or because of his hair was "made" or born more like a man than a child; and so the Targum adds,
``because he was wholly perfect, with the hair of his head and beard, and with his teeth and grinders:''but chiefly because of his hairiness, for Esau in the Arabic language signifies "covered" F6, as he was with hair: some say, a word in that language signifies a hairy garment made of camel's hair F7.
