C. F. Keil and Franz Delitzsch on Leviticus 20:9-18

Lev 20:9-18

Whoever cursed father or mother was to be punished with death (Lev 19:3); “His blood would be upon him.” The cursing of parents was a capital crime (see at Lev 17:4, and for the plural דּמיו Exo 22:1 and Gen 4:10), which was to return upon the doer of it, according to Gen 9:6. The same punishment was to be inflicted upon adultery (Lev 20:10, cf. Lev 18:20), carnal intercourse with a father’s wife (Lev 20:11, cf. Lev 18:7-8) or with a daughter-in-law (Lev 20:12, cf. Lev 18:17), sodomy (Lev 20:13, cf. Lev 18:22), sexual intercourse with a mother and her daughter, in which case the punishment was to be heightened by the burning of the criminals when put to death (Lev 20:14, cf. Lev 18:17), lying with a beast (Lev 20:15, Lev 20:16, cf. Lev 18:23), sexual intercourse with a half-sister (Lev 20:17, cf. Lev 18:9 and Lev 18:11), and lying with a menstruous woman (Lev 20:18, cf. Lev 18:19). The punishment of death, which was to be inflicted in all these cases upon both the criminals, and also upon the beast that had been abused (Lev 20:15, Lev 20:16), was to be by stoning, according to Lev 20:2, Lev 20:27, and Deu 22:21.; and by the burning (Lev 20:14) we are not to understand death by fire, or burning alive, but, as we may clearly see from Jos 7:15 and Jos 7:25, burning the corpse after death. This was also the case in Lev 21:9 and Gen 38:24.
