'Red' in the Bible

And the first came out red from head to foot like a robe of hair, and they gave him the name of Esau.

And Esau said to Jacob, Give me a full meal of that red soup, for I am overcome with need for food: for this reason he was named Edom.

And while she was in the act of giving birth, one of them put out his hand; and the woman who was with her put a red thread round his hand, saying, This one came out first.

And then his brother came out, with the red thread round his hand, and he was named Zerah.
