Genesis 16:4
And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was despised in her eyes.
And he went in unto Hagar, and she conceived,.... The formality of the marriage being over, he enjoyed her as his wife, and she immediately conceived by him:
and when she saw that she had conceived; when she perceived that she was with child:
her mistress was despised in her eyes; she thought herself above her, and treated her as her inferior, with contempt, and reproached her for her barrenness, as Peninnah did Hannah, 1 Samuel 1:6; and it was the more ungrateful, as it was at the motion of her mistress that she was given to Abram for wife.
