9  I wrote unto you in an epistle not to ^bcompany with fornicators:

  24  For the hearts of many were hardened, and their names were blotted out, that they were remembered no more among the people of God. And also many withdrew themselves from among them.

  57  And now I say unto you, all you that are desirous to follow the voice of the good shepherd, come ye out from the wicked, and be ye ^bseparate, and touch not their unclean things; and behold, their names shall be blotted out, that the names of the wicked shall not be numbered among the names of the righteous, that the word of God may be fulfilled, which saith: The names of the wicked shall not be mingled with the names of my people;

  17  Now I beseech you, brethren, mark them which cause ^bdivisions and offences contrary to the doctrine which ye have learned; and avoid them.
