Дварим 27:6 Ссылки в Мишне: Mishnah Middot & Mishnah Sotah

The stones both of the ascent and of the altar were taken from the valley of Bet Kerem. They dug into virgin soil and brought from there whole stones on which no iron had been lifted, since iron disqualifies by mere touch, though a flaw made by anything could disqualify. If one of them received a flaw, it was disqualified, but the rest were not. They were whitewashed twice a year, once at Pesah and once at Hag, and the Sanctuary was whitewashed once a year, at Pesah. Rabbi says: they were whitewashed every Friday with a cloth on account of the blood stains. The plaster was not laid on with an iron trowel, for fear that it might touch and disqualify. Since iron was created to shorten man's days and the altar was created to prolong man's days, and it is not right therefore that that which shortens should be lifted against that which prolongs.

How were the blessings and curses [pronounced]?When Israel crossed the Jordan and came to Mt. Gerizim and Mt. Ebal which are by Samaria, in the vicinity of Shechem which is near the terebinths of Moreh, as it is said, “Are they not the other side of the Jordan, [beyond the west road that is in the land of the Canaanites who dwell in the Arabah near Gilgal, by the terebinths of Moreh] (Deut. 11:30), and elsewhere it says, “And Abram passed through the land unto the place of Shechem unto the terebinth of Moreh” (Genesis 12:6) just as the terebinth of Moreh mentioned in this latter verse is Shechem, so the terebinth of Moreh mentioned in the former verse is Shechem. Six tribes went up Mt. Gerizim and six tribes went up Mt. Ebal, and the priests and Levites with the ark stood below in the middle, the priests surrounding the ark, the Levites [surrounding] the priests, and all Israel on this side and that side, as it is said, “And all Israel, with their elders, officials, and judges stood on both sides of the ark, facing the levitical priests” (Joshua 8:33). They turned their faces towards Mt. Gerizim and opened with the blessing: Blessed be anyone who does not make a graven or molten image”. And these and these respond amen. They then turned their faces towards Mt. Ebal and opened with the curse: “Cursed be anyone who makes a graven or molten image” (Deut. 27:15). And these and these respond amen. [So they continue] until they complete the blessings and curses. After that they brought the stones, built the altar and plastered it with plaster, and inscribed upon it all the words of the Torah in seventy languages, as it is said, “most distinctly (be’er hetev). Then they took the stones and went and spent the night in their place.
