Eze. 22: 30
NET ©
“I looked for a man from among them who would repair the wall and stand in the gap before me on behalf of the land, so that I would not destroy it, but I found no one."
Standing in the gap, like Moses had done: "So he said he would destroy them -- had not Moses, his chosen one, stood in the breach before him to keep his wrath from destroying them" (Psa 106:23)... (Jeremiah had been told no longer to pray for them: Jer 11:14.)
The Babylonians would come in and destroy Jerusalem.
Jesus was the Servant who could stand in the gap. No man was ever sufficient.
It is amazing how many prophecies are fulfilled and foreshadows of Christ in the OT. I love reading the OT just for that purpose.
