Ezekiel 9:2-6

And behold, six men came from the direction of the upper gate which faces north, each with his smashing weapon in his hand; and among them was one man clothed in linen with a scribe’s kit at his waist. And they came in and stood beside the bronze altar.

Then the glory of the God of Israel ascended from the cherub on which it had been, to the threshold of the temple. And He called to the man clothed in linen at whose waist was the scribe’s kit.

And the Lord said to him, “Go through the midst of the city, through the midst of Jerusalem, and make a mark on the foreheads of the people who groan and sigh over all the abominations which are being committed in its midst.”

But to the others He said in my presence, “Go through the city after him and strike; do not let your eye have pity and do not spare.

Utterly kill old men, young men, female virgins, little children, and women, but do not touch any person on whom is the mark; and you shall start from My sanctuary.” So they started with the elders who were before the temple.
