Isaiah 30:7

Concerning this; concerning this counsel or practice. Or, to her; to Jerusalem or Judah. Their strength is to sit still; it is safer and better for them to sit quietly at home, seeking to me for help. He seems industriously to use an ambiguous word, Rahab, which signifies both strength, as Job 9:13 Psalms 90:10, and Egypt, as Psalms 87:4 Isaiah 51:9, so called from its singular strength; to intimate that if they did not go to Rahab, Rahab, or what they expected from Rahab or Egypt, which was powerful succour, should come to them.
