Shewbread (Showbread): Provided by a Yearly Per Capita Tax

We also place ourselves under the obligation to contribute a third of a shekel yearly for the service of the house of our God:

…for the showbread, for the regular grain offerings and burnt offerings, for the Sabbath offerings, for the New Moons and appointed feasts, for the holy offerings, for the sin offerings to make atonement for Israel, and for all the duties of the house of our God.
