Joseph sends his brothers with gifts “To each of them, moreover, he gave a change of clothing; but to Benjamin, he gave three hundred pieces of silver and several*several Lit. “five”; cf. 43.34. changes of clothing” (Genesis 45:22).
We cling to our mistakes, and we repeat the mistakes of our parents. Just as Jacob discriminated against Joseph and created hatred between the brothers, so does Joseph when he gives Benjamin so much more.
The rabbis learn from this that a smart person is the one who learns from their own mistakes and from the mistakes of others.
