# General Information:

Yahweh compares the leaders of Jerusalem to a wall and himself to an invading army.

# a man from them who would build up a wall

"a man from among them who would act like he built a wall"

# stand before me in its breach

Its "breach" refers to a gap in the wall. This speaks of the man defending the people before Yahweh as if he were a warrior standing in the breach to defend the city.

# for the land so I would not destroy it

"for the people so that I would not destroy them"
