Sefer Ha-yashar, or, the Book of Jasher…
“ And Jacob said, Why have you dealt so ill with me to tell the king you had a brother? what is this thing that you have done unto me?19 And Judah said unto Jacob his father, Give the lad into my care and we will rise up and go down to Egypt and buy corn, and then return, and it shall be when we return if the lad be not with us, then let me bear thy blame forever.20 Hast thou seen all our infants weeping over thee through hunger and there is no power in thy hand to satisfy them? now let thy pity be roused for them and send our brother with us and we will go. ”
