Verses 1–8
DEUTERONOMY - CHAPTER TWENTY-SEVEN
Verses 1-8:
Moses and the elders of Israel gave instructions for a means by which all the people could be familiar with the Law which God gave from Sinai. This was a means commonly practiced in ancient times.
They were to erect pillars made of "great stones," and cover these pillars with plaster, sid, made of lime or gypsum. This coating provided a smooth, white surface upon which the words of the Law could be written. Specimens of such writing are extant today, which are as distinct and legible as when first written, two thousand years ago (Thomson, `Land and the Book’).
These pillars were to be erected on Mount Ebal. Compare this text with Joshua 8:30-32.
In addition to the pillars, an altar was to be erected, made of whole or uncut stones, see Exodus 20:25. The altar was to be on Mount Ebal, likely in close proximity to the pillars.
Israel was to offer on this altar sacrifices of burnt offerings (Le ch. 1) and peace offerings (Le ch. 3), in the same manner as they had done following the giving of the Law on Mount Sinai, Exodus 24:3-5.
The entire Law was to be written upon the plastered pillars, "very plainly," so there could be no misunderstanding, and so that all would be without excuse to know what God required.
Compare this text with Romans 1:18-20; Romans 2:12-16.
