What does Genesis 16:4 mean?
Sarai's plan to obtain a son, both for Abram and for herself, through her own servant Hagar, seems to be working. Hagar became Abram's second wife and she quickly becomes pregnant with his son. This is something which had not happened for Sarai in her entire life with Abram, including the 10 years in Canaan after God's latest promise of an heir (Genesis 16:3).However, this immediate pregnancy complicates Abram's family life. Hagar, now wife of Abram and bearer of his only child, begins to resent the woman who will claim that child as her own. Hagar may have wondered what she and Abram even needed Sarai for. If Hagar could give him children, wasn't Sarai unnecessary? Also, in that culture, barrenness was considered a sign of a defect, even divine disapproval. The fact that Hagar could immediately conceive, when Sarai could not after years and years, might have tempted Hagar to see herself as superior to her master. However it was motivated, Sarai feels Hagar's contempt, and it wounds her deeply, as the following verses will reveal.
