Charles Ellicott Commentary Ezekiel 29:7

"When they took hold of thee by thy hand, thou didst break, and didst rend all their shoulders; and when they leaned upon thee, thou brakest, and madest all their loins to be at a stand." — Ezekiel 29:7 (ASV)

All their loins to be at a stand.— The expression is a difficult one, but the more probable sense is, all their loins to shake. The reed breaks under the weight of the man who leans upon it, and pierces his shoulder as he falls, while in his consternation his loins tremble.
