Charles Ellicott Commentary 2 Kings 6:26

"And as the king of Israel was passing by upon the wall, there cried a woman unto him, saying, Help, my lord, O king." — 2 Kings 6:26 (ASV)

The king ... was passing by upon the wall. —On the broad rampart of the city, which was like what we see in old places such as Chester. The king went around to encourage the garrison and to oversee the defense. A woman in the street below, or perhaps on a housetop near the rampart, appeals to him for justice against her neighbor.
