John Calvin,
Calvin's Commentaries—Complete…
“ For as large bottles are broken with a slight blast; so by this single word, all their glory is extinguished, `the sons of the handmaid shall not be eternal inheritors.' In the meantime their insolence is to be patiently borne, so long as God shall loosen the rein to their tyranny. For the Apostles, formerly, were oppressed by the Jewish hypocrites of their age, with the same reproaches which these men now cast upon us. In the same way, Ishmael triumphed over Isaac, as if he had obtained the victory. Wherefore, we must not wonder, if our own age also has its Ishmaelites. ”
