In Genesis 12:18, Pharaoh rebukes Abram with nearly identical wording — another ruler discovering the patriarch lied about his wife being his sister, creating the same guilt scenario.

Genesis 12:19 completes the same rebuke: the ruler could have taken the woman as his wife unknowingly. The near-identical phrasing highlights the repeated pattern of deception.

Genesis 20:9 records Abimelech rebuking Abraham for the exact same deception with Sarah — a nearly identical confrontation that Isaac's situation echoes.

Genesis 20:10 continues Abimelech's questioning of Abraham about why he did this. Isaac faces the same inquiry from the same king, repeating his father's sin.

Proverbs 6:29 warns that touching another man's wife brings guilt — which is exactly the danger Abimelech describes. The proverb articulates the principle behind his fear.
