Ezekiel 16:61

Then thou shalt remember thy ways, the goodness of God leading at least a few to repentance, and be ashamed, when thou shalt receive thy sisters, thine elder and thy younger, representatives from various parts of the heathen world becoming partakers of the privileges formerly accorded to Israel alone; and I will give them unto thee for daughters, but not by the covenant, that is, not by that of the Old Testament, under which Israel had been chosen.
