Q. Abraham took a second wife. Jewish traditions say she was Hagar. Most accounts say he married Keturah after Sarah’s death. Can you share what you know on this topic?
The book of Genesis relates how God promised Abraham and Sarah that they would have a child of their own. But instead, as the customs of the time permitted, Sarah gave her female servant Hagar to Abraham as a concubine or secondary wife. Abraham and Hagar had a son named Ishmael.
Later God’s promise came true and Abraham and Sarah did have a child of their own named Isaac. Sarah wanted to make sure that Isaac would have the rights of the firstborn and be the heir, so she got Abraham to send Hagar and Ishmael away. It seems that this involved Abraham divorcing Hagar.
It must be acknowledged that Hagar is one of the figures in the Bible who is treated worst by the people who were supposed to be following and obeying God. But God provided for Hagar and Ishmael, and in response, Hagar gave God the name El-Roi, meaning The God Who Sees. Hagar recognized that God was aware of her situation and caring for her. And so Hagar is also the only figure in the Bible, as far as I know, who gave God a name. God himself revealed all of his other names.
Genesis also tells us that after Sarah died, Abraham married another woman, named Keturah. The two of them had six sons. But Abraham sent them to live in other places so that Isaac would be his undisputed heir.
So the woman Abraham married after the death of his first wife was Keturah. She was his second wife in that sense. However, while Sarah was still alive, Abraham was married to Hagar as his concubine. So in another sense, she may be considered his second wife.
