Romans 16:17-19

Young's Literal Translation

¹⁷ And I call upon you, brethren, to mark those who the divisions and the stumbling-blocks, contrary to the teaching that ye did learn, are causing, and turn ye away from them;

¹⁸ for such our Lord Jesus Christ do not serve, but their own belly; and through the good word and fair speech they deceive the hearts of the harmless,

¹⁹ for your obedience did reach to all; I rejoice, therefore, as regards you, and I wish you to be wise, indeed, as to the good, and harmless as to the evil;
