Ezekiel 4:3

4:3 Then for your part take an iron frying pan and set it up as an iron wall between you and the city. Set your face toward it. It is to be under siege; you are to besiege it. This is a sign for the house of Israel.

Ezekiel 24:17

24:17 Groan in silence for the dead, but do not perform mourning rites. Bind on your turban and put your sandals on your feet. Do not cover your lip and do not eat food brought by others.”
