Genesis 16:4 In-Context

2 Sarai said to Avram," See now, the LORD has restrained me from bearing. Please go in to my handmaid. It may be that I will obtain children by her." Avram listened to the voice of Sarai.
3 Sarai, Avram's wife, took Hagar the Mitzrian, her handmaid, after Avram had lived ten years in the land of Kana`an, and gave her to Avram her husband to be his wife.
4 He went in to Hagar, and she conceived. When she saw that she had conceived, her mistress was despised in her eyes.
5 Sarai said to Avram, "This wrong is your fault. I gave my handmaid into your bosom, and when she saw that she had conceived, I was despised in her eyes. The LORD judge between me and you."
6 But Avram said to Sarai, "Behold, your maid is in your hand. Do to her whatever is good in your eyes." Sarai dealt harshly with her, and she fled from her face.
