'Seven' in the Bible

There was a prophetess, Anna, the daughter of Phanuel, of the tribe of Asher. She was very old, and had lived with her husband for seven years after her marriage,

and also some women who had been healed of evil spirits and diseases: Mary, called Magdalene [from the city of Magdala in Galilee], from whom seven demons had come out,

Then it goes and brings seven other spirits more evil than itself, and they go in [the person] and live there; and the last state of that person becomes worse than the first.”

Even if he sins against you seven times a day, and returns to you seven times and says, ‘I repent,’ you must forgive him [that is, give up resentment and consider the offense recalled and annulled].”

Now there were seven brothers; and the first took a wife and died childless.

and the third married her, and in the same way all seven died, leaving no children.

So in the [life after] resurrection, whose wife does she become? For all seven had married her.”

And then, that very day two of them were going to a village called Emmaus, which was about seven miles from Jerusalem.
