She says, “My wrong.” The wrong here was the contempt, that is the contempt that was done to me, me upon you. Again, this was another, very well-established way of passing on a curse. I want to show you this by going to Genesis 27. This is the passage where Rebekah and Jacob were scheming to get the birthright and the blessing away from Isaac. So Isaac is blind and Rachel concocts this scheme where Jacob is going to make himself seem like Esau.
So she is making this oath that if indeed there is a curse, rather than come on Jacob it will come on her. Now that is at what Sarah did. She passed on her curse to Abram. Let us go back to another place and this time it is God speaking.
