2 Timothy 2:15; 2 Thessalonians 3:6; 1 Timothy 6:5

15 Be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth.

6 But we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother who walks disorderly and not according to the tradition which he received from us.

5 useless wranglings of men of corrupt minds and destitute of the truth, who suppose that godliness is a means of gain. From such withdraw yourself.
