'Two' in the Bible

That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:

having the golden altar of incense and the ark of the covenant covered entirely with gold. This contained a golden jar which held the manna, and the rod of Aaron that sprouted, and the [two stone] tablets of the covenant [inscribed with the Ten Commandments];

He that despised Moses' law died without mercy under two or three witnesses:

By faith Jacob gave a blessing to the two sons of Joseph, when he was near to death; and gave God worship, supported by his stick.

They were stoned, they were sawed in two, they died by the sword, they wandered about in sheepskins, in goatskins, destitute, afflicted, and mistreated.
