as Moses the servant of Yahweh commanded the children of Israel, as it is written in the book of the law of Moses, an altar of uncut stones, on which no man had lifted up any iron: and they offered thereon burnt offerings to Yahweh, and sacrificed peace-offerings.
"The method of plastering stones and then printing on them came originally from Egypt; thus, the letters were probably painted in red. So we can imagine large whitewashed monoliths with red Hebrew characters spelling out the Ten Commandments, and possibly the blessings and curses of the Law as well (cf. Deuteronomy 28). This structure was the first public display of the Law." [Note: Hughes, p. 101.]
