Genesis 12:17 - Exposition

And the Lord plagued (literally, struck ) Pharaoh and his house with great plagues (or strokes, either of disease or death, or some other calamity—an indication that Pharaoh was not entirely innocent) because of Sarai Abram's wife . The effect of this was to lead to the discovery, not through the aid of the Egyptian priests (Josephus), but either through a special revelation granted to him, as afterwards ( Genesis 20:6 ) to Abimelech in a dream (Chrysostom), or through the confession of Sarai herself ( A Lapide), or through the servants of Abraham (Kurtz).
