But the Lord struck Pharaoh and his house with great plagues because of Sarai, Abram’s wife.
Genesis 12:17 (NASB)
The rabbis note this phrase "because of Sarai" is עַל־דְּבַר שָׂרַי, which can be read literally as "at the word of Sarai," and this changes the tenor of the story entirely.
The Midrash states, "at her orders: she said to the angel, 'smite' and he smote."
This is not only a story of Abram, but of Sarai.
