Adam Clarke on Genesis 43:23

And he said - The address of the steward in this verse plainly proves that the knowledge of the true God was in Egypt. It is probable that the steward himself was a Hebrew, and that Joseph had given him intimation of the whole affair; and though he was not at liberty to reveal it, yet he gives them assurances that the whole business would issue happily.

I had your money - כספכם בא אלי caspechem ba elai, your money comes to me. As I am the steward, the cash for the corn belongs to me. Ye have no reason to be apprehensive of any evil; the whole transaction is between myself and you; receive therefore the money as a present from the God of your father, no matter whose hands he makes use of to convey it. The conduct of the steward, as well as his words, had a great tendency to relieve their burdened minds.
