"Ritual law"

God gives Moshe and Aharon instructions about the red cow, which is needed to purify one who has had contact with a dead body. Moshe draws water from a stone by striking it, instead of speaking to it, as he had been commanded by God. As a result, he will not enter the Promised Land. Miryam and Aharon die; El‘azar, son of Aharon, succeeds him as High Priest. The camp is attacked by serpents and Moses is instructed to place a copper serpent on a high place; those who look at her will be healed. Emorite lands are conquered east of the Jordan River.
