Verses with the word doer in the New Testament (4 verses):
2 Timothy 2:9
Wherein I suffer trouble, as an evil doer, even unto bonds; but the word of God is not bound.
For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass:
But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.
