Devarim 27:1 In-Context

1 7 And Moshe with the zekenim of Yisroel commanded the people, saying, Be shomer over all the mitzvot which I command you today.

2 And it shall be on the yom when ye shall pass over Yarden unto Ha’Aretz which Hashem Eloheicha giveth thee, that thou shalt set thee up avanim gedolot, and plaster them with plaster;

3 And thou shalt write upon them kol divrei hatorah hazot, when thou art passed over, that thou mayest go in unto Ha’Aretz which Hashem Eloheicha giveth thee, Eretz zavat cholov udevash; as Hashem Elohei Avoteicha hath promised thee.

4 Therefore it shall be when ye be gone over Yarden, that ye shall set up these avanim, which I command you today, in Mt Eival, and thou shalt plaster them with plaster.

5 And there shalt thou build a mizbe’ach unto Hashem Eloheicha, a mizbe’ach of avanim; thou shalt not use any barzel (iron [tool]) upon them.
