Jamieson, Fausset & Brown

For what if some did not believe?--It is the unbelief of the great body of the nation which the apostle points at; but as it sufficed for his argument to put the supposition thus gently, he uses this word "some" to soften prejudice. shall their unbelief make the faith of God--or, "faithfulness of God." of none effect?--"nullify," "invalidate" it.
