C. F. Keil and Franz Delitzsch on Leviticus 24:17-18

Lev 24:17-18

The decision asked for from God concerning the crime of the blasphemer, who was the son of an Egyptian, and therefore not a member of the congregation of Jehovah, furnished the occasion for God to repeat those laws respecting murder or personal injury inflicted upon a man, which had hitherto been given for the Israelites alone (Exo 21:12.), and to proclaim their validity in the case of the foreigner also (Lev 24:17, Lev 24:21, Lev 24:22). To these there are appended the kindred commandments concerning the killing of cattle (Lev 24:18, Lev 24:21, Lev 24:22), which had not been given, it is true, expressis verbis, but were contained implicite in the rights of Israel (Exo 21:33.), and are also extended to foreigners. אדם נפשׁ הכּה, to smite the soul of a man, i.e., to put him to death; - the expression “soul of a beast,” in Lev 24:18, is to be understood in the same sense.
