'Six' in the Bible

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

[Among] the cities which you give to the Levites shall be the six cities of refuge, which you shall provide for the one who commits manslaughter to flee to; and in addition to them you shall give forty-two cities [to the Levites].

The cities which you are to provide shall be your six cities of refuge.

These six cities shall be a refuge for the Israelites and for the stranger and the resident alien among them; so that anyone who kills a person unintentionally may escape there.
