30 Heb “And from your seed you shall not give to cause to pass over to Molech.” (cf. also the ) has “to cause to serve” rather than “to cause to pass over.” For detailed remarks on Molech and Molech worship see N. H. Snaith, Leviticus and Numbers (), 87–88; P. J. Budd, Leviticus (), 259–60; and J. E. Hartley, Leviticus (), , and the literature cited there. It could refer to either human sacrifice or a devotion of children to some sort of service of Molech, perhaps of a sexual sort (cf. Lev 20:2–5; 2 Kgs 23:10, etc.). The inclusion of this prohibition against Molech worship here may be due to some sexual connection of this kind, or perhaps simply to the lexical link between זֶרַע (zera’) meaning “seed, semen” in v. 20 but “offspring” in v. 21.
31 Heb “and you shall not profane.” Regarding “profane,” see the note on above.
