'Seven' in the Bible

Then he goes and takes with him seven other spirits worse than himself, and they go in and make it their living-place: and the last condition of that man is worse than the first. Even so will it be with this evil generation.

And Jesus says to them, How much bread have you? And they said, Seven cakes, and some small fishes.

And he took the seven cakes of bread and the fishes; and having given praise, he gave the broken bread to the disciples, and the disciples gave it to the people.

And they all took food, and had enough; and they took up of the broken bits, seven baskets full.

Or the seven cakes of bread of the four thousand, and the number of baskets you took up?

Then Peter came and said to him, Lord, what number of times may my brother do wrong against me, and I give him forgiveness? till seven times?

Jesus says to him, I say not to you, Till seven times; but, Till seventy times seven.

Now there were among us seven brothers; and the first was married and at his death, having no seed, gave his wife to his brother;

When they come back from the dead, then, whose wife will she be of the seven? because they all had her.
