'Six' in the Bible

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

The cities which you shall give to the Levites shall be the six cities of refuge, which you shall give for the manslayer to flee to; and in addition to them you shall give forty-two cities.

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

These six cities shall be for refuge for the sons of Israel, and for the alien and for the sojourner among them; that anyone who kills a person unintentionally may flee there.
