He wrote there on the stones a copy of the law of Moses, which he wrote, in the presence of the children of Israel.
The extent of the passages from the Mosaic Law that the people copied on the stone monuments is not clear from this passage. Deuteronomy 27 seems to imply the Ten Commandments. "The blessing and the curse" (Joshua 8:34) may be a synonym for "all the words of the law" (i.e., the Ten Commandments), rather than a reference to the specific blessings and curses listed previously and recited here (Deuteronomy 28). However, another possibility is that "the blessing and the curse" may refer to Deuteronomy 28. Some scholars believe the Israelites inscribed the whole Book of Deuteronomy on a stone. This is possible since the Behistun Inscription, also written on a stone monolith in Iran, is three times the length of Deuteronomy.
