"You shall bring from your dwellings two wave-loaves of two tenth measures"Leviticus 23:17.

On the holiday of Atzeret [Shavuot], we are commanded to bring two loaves of leavened bread in the Holy Temple, together with an accompanying animal Peace Offering (in addition to the holiday's additional offering).

These two loaves as well as the sacrifices are eaten by the kohanim (priests).
