Commentaries:
Adam Clarke
For I will cleanse their blood - nikkeythi , I will avenge the slaughter and martyrdom of my people, which I have not yet avenged.
Persecuting nations and persecuting Churches shall all come, sooner or later, under the stroke of vindictive justice.
For the Lord dwelleth in Zion - He shall be the life, soul, spirit, and defense of his Church for ever. This prophet, who has many things similar to Ezekiel, ends his prophecy nearly in the same way:
Ezekiel says of the glory of the Church, Yehovah shammah , The Lord Is There.
Joel says, Yehovah shochen betsiyon , The Lord Dwelleth in Zion.
Both point out the continued indwelling of Christ among his people.
