The Mishnah recounted the history of decentralized sacrifice. Before the Tabernacle, high places were permitted, and Israelite firstborn performed the sacrifices. After the Israelites set up the Tabernacle, high places were forbidden, and priests performed the services. When the Israelites entered the Promised Land and came to Gilgal, high places were again permitted. When the Israelites came to Shiloh, high places were again forbidden. The Tabernacle there had no roof, but consisted of a stone structure covered with cloth. The Mishnah interpreted the Tabernacle at Shiloh to be the "rest" to which Moses referred in . When the Israelites came to Nob and Gibeon, high places were again permitted. And when the Israelites came to Jerusalem, high places were forbidden and never again permitted. The Mishnah interpreted the sanctuary in Jerusalem to be "the inheritance" to which Moses referred in . The Mishnah explained the different practices at the various high places when high places were permitted. The Mishnah taught that there was no difference between a Great Altar (at the Tabernacle or the Temple) and a small altar (a local high place), except that the Israelites had to bring obligatory sacrifices that had a fixed time, like the Passover sacrifice, to the Great Altar. Further, the Mishnah explained that there was no difference between Shiloh and Jerusalem except that in Shiloh they ate minor sacrifices and second tithes ("ma'aser sheni") anywhere within sight of Shiloh, whereas at Jerusalem they were eaten within the wall. And the sanctity of Shiloh was followed by a period when high places were permitted, while after the sanctity of Jerusalem high places were no longer permitted.
