²³ The son born from the woman servant who was owned by someone was like any other birth. The son born from the free woman was different. That son had been promised by God. ²⁴ Think of it like this: These two women show God’s two ways of working with His people. The children born from Hagar are under the Law given on Mount Sinai. They will be servants who are owned by someone and will always be told what to do! ²⁵ Hagar is known as Mount Sinai in the country of Arabia. She is as Jerusalem is today, because she and her children are not free to do what they want to do.
