Now it was to Abraham that the promises were made, 'and to his offspring.' It was not said 'to his offsprings,' as if many persons were meant, but the words were 'to thy offspring,' showing that one person was meant--and that was Christ.

This story may be taken as an allegory. The women stand for two Covenants. One Covenant, given from Mount Sinai, produces a race of slaves and is represented by Hagar

(The word Hagar meaning in Arabia Mount Sinai) and it ranks with the Jerusalem of to-day, for she and her children are in slavery.
