41 Then Moses set apart three cities of refuge east of the Jordan River. 42 Anyone who killed another person unintentionally, without previous hostility, could flee there to live in safety. 43 These were the cities: Bezer on the wilderness plateau for the tribe of Reuben; Ramoth in Gilead for the tribe of Gad; Golan in Bashan for the tribe of Manasseh.
44 This is the body of instruction that Moses presented to the Israelites. 45 These are the laws, decrees, and regulations that Moses gave to the people of Israel when they left Egypt, 46 and as they camped in the valley near Beth-peor east of the Jordan River. (This land was formerly occupied by the Amorites under King Sihon, who ruled from Heshbon. But Moses and the Israelites destroyed him and his people when they came up from Egypt. 47 Israel took possession of his land and that of King Og of Bashan-the two Amorite kings east of the Jordan. 48 So Israel conquered the entire area from Aroer at the edge of the Arnon Gorge all the way to Mount Sirion, also called Mount Hermon. 49 And they conquered the eastern bank of the Jordan River as far south as the Dead Sea, below the slopes of Pisgah.)

Here is the introduction to another discourse, or sermon, Moses preached to Israel, which we have in the following chapters. He sets the law before them, as the rule they were to work by, the way they were to walk in. He sets it before them, as the glass in which they were to see their natural face, that, looking into this perfect law of liberty, they might continue therein. These are the laws, given when Israel was newly come out of Egypt; and they were now repeated. Moses gave these laws in charge, while they encamped over against Beth-peor, an idol place of the Moabites. Their present triumphs were a powerful argument for obedience. And we should understand our own situation as sinners, and the nature of that gracious covenant to which we are invited. Therein greater things are shown to us than ever Israel saw from mount Sinai; greater mercies are given to us than they experienced in the wilderness, or in Canaan. One speaks to us, who is of infinitely greater dignity than Moses; who bare our sins upon the cross; and pleads with us by His dying love.
