'Sleeves' in the Bible

Now Israel (Jacob) loved Joseph more than all his children, because he was the son of his old age; and he made him a [distinctive] multicolored tunic.

And it happened [that] as Joseph came to his brothers they stripped Joseph of his robe, the robe with long sleeves, that [was] upon him.

Then they sent the robe with long sleeves and they brought [it] to their father and said, "We found this; please examine [it]. [Is] it the robe of your son or not?"
