Thou didst blaspheme, Heb. bless. Blessing is put for cursing and blaspheming, as Job_1:5 2:9, so also here, as is apparent, because his blessing God and the king had been no crime. It is a figure called euphemisms. God would have blasphemy so much abhorred, that it should not easily and unnecessarily be named by its proper name. Compare Psa_16:4.
Carry him out, to the place where malefactors were punished, which was out of the city, Lev_24:23Jos_7:24Mar_15:20Heb_13:12, partly to show that they were unworthy of all human society, and abhorred by all the people; and partly because the place where they were killed was thereby ceremonially polluted.
Stone him; the proper punishment of blasphemers, Lev_24:15,16.
That he may die; as one that cursed his God, and his political father, his king. See Exo_21:17 12:28.
