Genesis 20:16
And unto Sarah he said, Behold, I have given thy brother a thousand pieces of silver: behold, he is to thee a covering of the eyes, unto all that are with thee, and with all other: thus she was reproved.
Cross-reference
Genesis 20:5
Historical context
In Genesis 20:5, Abimelech protests his innocence — the restitution of silver in 20:16 flows directly from this defense of acting unknowingly.
Genesis 26:11
Parallel
In Genesis 26:11, Abimelech issues the same protective decree over Isaac and Rebekah — the wife-sister deception pattern recurs with the same king.
