20:26 not clean. See especially Lev. 7:19–21. Laws of cleanliness are covered most fully in Lev. 11–15, though references to “clean” and “unclean” are frequent throughout the Pentateuch (Gen. 7:2; Lev. 5:2; Num. 5:2; Deut. 14:3–21; etc.). The point is not physical but ritual or religious uncleanness.
