Genesis 42:26-28

"And they laded their asses with their grain, and departed thence. And as one of them opened his sack to give his ass provender in the lodging-place, he espied his money; and, behold, it was in the mouth of his sack. And he said unto his brethren, My money is restored; and lo, it is even in my sack: and their heart failed them, and they turned trembling one to another saying, What is this that God hath done unto us?"

The mention here of only one of the brothers finding his money, and later of all of them finding their money after they arrive home, is no evidence whatever of two different, contradictory sources, a favorite allegation of unbelievers. On the other hand, this is exactly the way it happened. It was by chance that one of them opened a sack of grain to feed his ass, and that that particular sack was the one in which his money was restored. It would have been an exceedingly difficult and dangerous task to dismantle the whole shipment and search all the sacks at a lodging-place, where the curiosity of others and the cupidity of thieves would have been an added inducement for a hostile attack. One sack with the money restored was the only excuse which Joseph needed to have them all arrested, an event which they, at the time, might have expected. The full extent of the restored purchase price did not come to light until the entire cargo was unloaded AFTER they reached home.
