Dig thou through the wall in their sight, and carry out thereby.
Dig thou through the wall in their sight. As Zedekiah was to escape like one digging through a wall, furtively to effect an escape (Ezekiel 12:12).
Carry out - namely, "thy stuff" (Ezekiel 12:4).
Thereby - by the opening in the wall. Zedekiah escaped "by the gate between the two walls" (Jeremiah 39:4).
