'Doer' in the Bible

And I am this day weak, though anointed king; and these men, the sons of Zeruiah, are too hard for me: Jehovah reward the doer of evil according to his wickedness!

Love Jehovah, all ye his saints. Jehovah preserveth the faithful, and plentifully requiteth the proud doer.

Thus saith Jehovah the doer of it, Jehovah that formeth it to establish it, Jehovah is his name:

For if any man be a hearer of the word and not a doer, he is like to a man considering his natural face in a mirror:

But he that fixes his view on the perfect law, that of liberty, and abides in it, being not a forgetful hearer but a doer of the work, he shall be blessed in his doing.

Speak not against one another, brethren. He that speaks against his brother, or judges his brother, speaks against the law and judges the law. But if thou judgest the law, thou art not doer of the law, but judge.
