John 7:17-19

Wycliffe Bible

¹⁷ If any man will do his will, he shall know of the teaching, whether it be of God, or [whether] I speak of myself.

¹⁸ He that speaketh of himself, seeketh his own glory; but he that seeketh the glory of him that sent him, is soothfast, and unrightwiseness is not in him.

¹⁹ Whether Moses gave not to you a law, and none of you doeth the law [and no man of you keepeth the law]? What seek ye to slay me?
