Genesis 44:32-36

For thy servant became surety for the lad unto my father, saying, If I bring him not unto thee, then I shall bear the blame to my father for ever.

Now therefore, I pray thee, let thy servant abide instead of the lad a bondman to my lord; and let the lad go up with his brethren.

For how shall I go up to my father, and the lad be not with me? lest peradventure I see the evil that shall come on my father.
