Now look, I strike My hands together against your unjust gain and against the blood you have shed in your midst.
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, therefore, I have smitten mine hand at thy dishonest gain which thou hast made,.... As one amazed at it; or as filled with indignation against it; or as grieved and distressed at it; so Jarchi and Kimchi: or else as rejoicing at the punishment going to be inflicted on them for it.
smitten mine hand--in token of the indignant vengeance which I will execute on thee (see on Eze 21:17).
