'Breach' in the Bible

I sought for a man among them to build the wall and stand in the breach in my presence on behalf of the land so that it won't be destroyed, but I found no one,

""He'll direct the blows of his battering rams against your walls and will breach your fortified towers with axes.

By reason of the abundance of his horses their dust shall cover thee: thy walls shall shake at the noise of the horsemen, and of the wheels, and of the chariots, when he shall enter into thy gates, as men enter into a city wherein is made a breach.

Elders of Gebal and its wise men have been in thee, Strengthening thy breach; All ships of the sea and their mariners, Have been in thee, to trade with thy merchandise.

Thy wealth and thy remnants, Thy merchandise, thy mariners, And thy pilots, strengtheners of thy breach, And the traders of thy merchandise, And all thy men of war, who are in thee, And in all thine assembly that is in thy midst, Fall into the heart of the seas in the day of thy fall,
