John Gill Commentary Ezekiel 22:6

"Behold, the princes of Israel, every one according to his power, have been in thee to shed blood." — Ezekiel 22:6 (ASV)

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 within you exerted 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 most, to exceed each other in this abominable sin.
