2 Kings 10:8

Lay them at the entering in of the gate The place of judicature, to signify that this was an act of God's righteous judgment: and this being the place of public concourse for justice and other business, and where people were continually passing and repassing, the laying them there was to expose them to public view, that all might know there was no one left of Ahab's posterity to reign over them.
