Coat of many colours
From the Bible, Genesis 37:3 (King James Version):
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.
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;
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 sons coat or no.
