'Eight' in the Bible

Then God gave Abraham the covenant of circumcision, and so he became the father of Isaac and circumcised him when he was eight days old, and Isaac became the father of Jacob, and Jacob of the twelve patriarchs.

And there he found a certain man named AEneas, which had kept his bed eight years, and was sick of the palsy.

When he had spent not more than eight or 10 days among them, he went down to Caesarea. The next day, seated at the judge’s bench, he commanded Paul to be brought in.
