'Six' in the Bible

They brought their offering before the Lord, six covered carts and twelve oxen -- one cart for every two of the leaders, and an ox for each one; and they presented them in front of the tabernacle.

Now from these towns that you will give to the Levites you must select six towns of refuge to which a person who has killed someone may flee. And you must give them forty-two other towns.

These towns that you must give shall be your six towns for refuge.

These six towns will be places of refuge for the Israelites, and for the foreigner, and for the settler among them, so that anyone who kills any person accidentally may flee there.
