And on the wall of Ophel he built much.
Building on Ophel
Ophel means “the mount.” Where was the mount? On the southern slope. Why did the king build so much on Ophel? Because it was most accessible to the enemy. Like a wise commander he remembered that no man is stronger than his weakest point, and that no fortification is stronger than its frailest part; so the king built much where the wall was weakest, or where the access of the enemy was most open; and in doing so he gathered up and represented the wisdom and experience of the ages, and anticipated what we and all the sons of time ought to do. What is your weakest point in life? Build much there. (J. Parker, D.D.)
