“Euen so haue these also now not beleeued, that through your mercy they also may obtaine mercy.”
1611 King James Version (KJV)
Ro 11:31 Even so have these also now not believed. These Jews who were now in unbelief. Their disobedience had opened the door for the Gentiles. That through your mercy they may also obtain mercy. But the mercy shown the Gentiles, the fact that they are honoring and worshiping God, shall be a means of converting the Jews. Thus shall "they also [the Jews] may also obtain mercy".
