משנה אויף שמות 28:43

The following sacrifices were offered in the Tabernacle sacrifices consecrated for the Tabernacle: Public sacrifices were offered in the Tabernacle, and private sacrifices were offered at a bamah. If private sacrifices were consecrated for the Tabernacle, they must be offered in the Tabernacle; yet if one offered them at a bamah, he is not liable. What is the difference between the bamah of an individual and the bamah of the congregation? Laying [of hands], slaughtering in the north, sprinkling around [the altar], waving and presenting, (Rabbi Judah says: there were no meal-offerings at the bamah); priesthood, sacrificial vestments, ministering vessels, a sweet fragrance, a line of demarcation for [the sprinkling of] the blood, and the washing of hands and feet. But [the prohibitions of] time, remnant and defilement were the same in both.
