Will ne’er forsake or injure you;
My SECOND, coming from the street
You often trample under feet;
My THIRD you sleep on every night,
Serene and calm, without affright;
My WHOLE is what you should not be
When talking with your friends or me.
My FIRST is a little river in England that gave name to a celebrated university; my SECOND is always near; my THIRD sounds like several large bodies of water; and my WHOLE is the name of a Persian monarch, the neighing of whose horse gave him a kingdom and a crown.
