Isaías 33

Isaías 33:13

He speaks moreover concerning our ears, how He hath circumcised both them and our heart. The Lord saith in the prophet, "In the hearing of the ear they obeyed me." And again He saith, "By hearing, those shall hear who are afar off; they shall know what I have done." And, "Be ye circumcised in your hearts, saith the Lord." ... Therefore He hath circumcised our ears, that we might hear His word and believe. — The Epistle of Barnabas, Chapter IX
