Charles Ellicott Commentary Ezekiel 9:5

"And to the others he said in my hearing, Go ye through the city after him, and smite: let not your eye spare, neither have ye pity;" — Ezekiel 9:5 (ASV)

Go ye after him.— No interval is allowed. Here, as in the corresponding visions in Revelation referred to above, judgment waits only until those whom mercy will spare have been protected (Compare to the deliverance of Lot, Genesis 19:22–25).

The destruction was to be utter and complete, and was to begin at the sanctuary, where the gross sin of the people had culminated.

This is one of those many important passages in Scripture (Luke 23:30; Revelation 6:16, and others) in which God reveals Himself as one who will ultimately take vengeance without pity upon those who have rejected and insulted His mercy and long-suffering kindness. The revelation of future wrath is no less clear and distinct than that of love to those who trust in Him.
