(Devarim 12:8) "You shall not do as all that we do here today": As long as the mishkan (the tabernacle) had not been established, the bamoth (individual altars) were permitted, and the (sacrificial) service was performed by the first-born. When the mishkan was established, the bamoth were forbidden and the service was performed by the Cohanim.

Before they came to Shiloh, the bamoth were permitted. After they came to Shiloh, the bamoth were forbidden. When they came to Nov and Giveon, the bamoth were permitted. When they came to Jerusalem, the bamoth were forbidden, and not permitted again, as it is written "You shall not do as all that we do here today":

We move the mishkan. Today, bamoth are forbidden to us. When we come to Eretz Yisrael, we do not move the mishkan and bamoth are permitted to us.

R. Yehudah says: I might think that the congregation sacrificed on a bamah; it is, therefore, written "a man, all that is fitting in his eyes" — An individual sacrifices on a bamah, but not the congregation.

"all that is fitting in his eyes": All that is vowed and donated is sacrificed on an individual bamah; and all that is not vowed and donated is not sacrificed on an individual bamah.

The sages say: "here today" we sacrifice sin-offerings and guilt-offerings, but when we come to Eretz Yisrael, we will not sacrifice sin-offerings and guilt-offerings, even upon a great bamah.
