'Evil One' in the Bible

and every perfect gift, but no evil one, is from above, and cometh down from the Father of lights, with whom there is no variation, nor shadow of turning:

This wisdom is not from heaven, but is of the earth and the flesh and the Evil One.

For this cause be ruled by God; but make war on the Evil One and he will be put to flight before you.

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.
