"But at the end of forty years there appeared to him in the Desert of Mount Sinai an angel in the middle of a flame of fire in a bush.

This is he who was among the Congregation in the Desert, together with the angel who spoke to him on Mount Sinai and with our forefathers, who received ever-living utterances to hand on to us.

All this is allegorical; for the women represent two Covenants. One has its origin on Mount Sinai, and bears children destined for slavery.

This is Hagar; for the name Hagar stands for Mount Sinai in Arabia, and corresponds to the present Jerusalem, which is in bondage together with her children.
