‘And Sarai said to Abram, “My wrong be on you. I gave my handmaid for you to make love to (into your bosom) and when she saw that she had conceived I was of little account in her eyes. Yahweh judge between you and me”.'
“My wrong be on you.” This is an official plea for legal protection. Sarai now wants Abram as head of the family tribe to remedy the situation. She dare not act on her own. She has given her slave to her husband and her slave is now no longer just a handmaid. He is the one who has the authority, and all that is done in the tribe is in his hands. He must be the one to put right the wrong done to her.
“Yahweh judge between you and me.” She reminds him that he must consider what Yahweh's verdict would be. Her insistence is that she be firmly reinstated as his principal wife with the authority going with such a position, a position that Hagar is undermining.
