There are two voices with me in the night,
Easing my grief. The God of Israel saith,
``I am the Lord thy God which vanquisheth.
See that thou walk unswerving in my sight,
So shall thy enemies thy footstool be.
I will avenge.'' Then wake I suddenly,
And, as a man new armoured for the fight,
I shout aloud against my enemy.

Anon, another speaks, a voice of care
With sorrow laden and akin to grief,
``My son,'' it saith, ``What is my will with thee?
The burden of my sorrows thou shalt share.
With thieves thou too shalt be accounted thief,
And in my kingdom thou shalt sup with me.''

Wilfrid Scawen Blunt
