In telling the story of the sale of Yosef, the Torah says that Reuven suggested putting Yosef in the pit so that he could come back and save him later.
When Reuven came back to discover that Yosef was no longer there, he said:
וַיָּ֥שָׁב אֶל־אֶחָ֖יו וַיֹּאמַ֑ר הַיֶּ֣לֶד אֵינֶ֔נּוּ וַֽאֲנִ֖י אָ֥נָה אֲנִי־בָֽא
Some say that the last word on the line is a kri uktiv, and it should say "עניבה", a necktie, and thus be read "He returned to his brothers and said, 'The boy is not with us, and where is my tie?'".
What was so special about Reuven's tie, and what happened to it?
