'Evil One' in the Bible

the field is the world; the good seed are the sons of the kingdom; but the darnel are the sons of the evil one.

But God judges those who are outside. Therefore put out from you the evil one.

I write to you, fathers, because you have known Him who is from the beginning. I write to you, young men, because you have overcome the evil one. I write to you, little children, because you have known the Father.

I write to you, fathers, because you have known Him who is from the beginning. I have written to you, young men, because you are strong, and the Word of God abides in you, and you have overcome the evil one.

not as Cain who was of the evil one, and killed his brother. And for what did he kill him? Because his own works were evil, and his brother's things were righteous.

We know that everyone who has been born of God does not continue to sin, but the one born of God guards himself, and the evil one does not touch him.
