Ecclesiastes 9:14,15

There was a little city, and few men within it; and there came a great king against it, and besieged it, and built great bulwarks against it:

A little city ... So Abel, which the wisdom of one woman saved from destruction by Joab, who cast up a bank against it, when the rebel Sheba was in it ().

Bulwarks - military works of besiegers.

No man remembered ... - (.)
