Now Israel loved Joseph more than all his children, because he was the son of his old age: and he made him a coat of many colours.
Genesis 37:23:
And it came to pass, when Joseph was come unto his brethren, that they stript Joseph out of his coat, his coat of many colours that was on him;
Genesis 37:32:
And they sent the coat of many colours, and they brought it to their father; and said, This have we found: know now whether it be thy son’s coat or no.
