and Isaac trembleth a very great trembling, and saith, 'Who, now, is he who hath provided provision, and bringeth in to me, and I eat of all before thou comest in, and I bless him? -- yea, blessed is he.'

He said to his brothers, “My money has been returned! It’s here in my bag.” Their hearts sank. Trembling, they turned to one another and said, “What is this that God has done to us?”
