“After ¹  forty years had passed, an angel appeared to him in the desert ²  of Mount Sinai, in the flame of a burning bush. ³ 

These things may be treated as an allegory, ¹  for these women represent two covenants. One is from Mount Sinai bearing children for slavery; this is Hagar.

Now Hagar represents Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.

This is the man who was in the congregation ¹  in the wilderness ²  with the angel who spoke to him at Mount Sinai, and with our ancestors, ³  and he ⁴  received living oracles ⁵  to give to you. ⁶
