The cities of refuge typify the all-inclusive Christ as the embodiment of the redeeming God, into whom mistaken sinners can flee for refuge. Christ was delivered by God into the hands of sinners (Acts 2:23; Rom. 4:25), who mistakenly put Him to death (Luke 23:34; 1 Cor. 2:8). If any sinner repents, God will regard him as a mistaken sinner and will forgive him (Luke 24:47; Acts 2:38). Such a one may flee into Christ. But if anyone refuses the gospel and does not repent, God will regard him as a willful sinner, one who is destined to perish (v. 16; John 3:16-18).
There were six cities of refuge, three on each side of the Jordan (v. 14). The number six signifies mistake-making man, who was created by God on the sixth day (Gen. 1:26-27, 31). The number three signifies the Triune God as the refuge for the man who makes mistakes. The number two (the two sets of three cities each) signifies a testimony standing in the universe, testifying and declaring to the universe that the Triune God is living on earth among human beings to be their city of refuge.
