Behold, the princes of Israel, every one were in thee to their power to shed blood.
In these verses the prophet by a commission from Heaven sits as a judge upon the bench, and Jerusalem is made to hold up her hand as a prisoner at the bar; and, if prophets were set over other nations, much more over God's nation, Jer 1:10. This prophet is authorized to judge the bloody city, the city of bloods.
Commenting on Ezekiel 22:1-16
Behold, the princes of Israel,.... Those that belonged to the royal family, or the nobles of the land, or the members of the grand sanhedrim of the nation: everyone were in thee to their power to shed blood; everyone exerted himself to the uttermost, according to his ability, to shed blood, or cause it to be shed; everyone strove, as it were, who should shed...
Rather, "The princes . . . each according to his power, were in thee, to shed blood" (as if this was the only object of their existence). "Power," literally, "arm"; they, who ought to have been patterns of justice, made their own arm of might their only law.
