Psalms 48:13

Mark ye well her bulwarks, consider her palaces; that ye may tell it to the generation following.

Mark ye her bulwarks, consider her palaces. The "bulwarks" indicate the outer circuit of the city; the "palaces" the interior. "Consider" - literally, divide; i:e., accurately contemplate, one by one: parallel to "tell."

That ye may tell it to the generation following - in order that they may glorify the God who performed such a deliverance for His people, and regard it as a pledge of future deliverances in times of danger.
