Charles Ellicott Commentary Ezekiel 21:12

"Cry and wail, son of man; for it is upon my people, it is upon all the princes of Israel: they are delivered over to the sword with my people; smite therefore upon thy thigh." — Ezekiel 21:12 (ASV)

Smite therefore upon your thigh. —A mark of extreme grief .

The connection of Ezekiel 21:11-12 with the objection in Ezekiel 21:10 is this: you think there is security for you in the promise to Judah. Do not deceive yourselves, but prepare for sorrow and desolation.
