Deuteronomy 27:3

All the words of this law - i. e. all the laws revealed from God to the people by Moses, regarded by the Jews as 613 (compare Numbers 15:38 note). The exhibition of laws in this manner on stones, pillars, or tables, was familiar to the ancients. The laws were probably graven in the stone (“very plainly,” Deuteronomy 27:8 is by some rendered “scoop it out well”), as are for the most part the Egyptian hieroglyphics, the “plaister” being afterward added to protect the inscription from the weather.
