Analysis of Sir Walter Raleigh to His Son

Three things there be that prosper up apace
And flourish, whilst they grow asunder far,
But on a day, they meet all in one place,
And when they meet, they one another mar;
And they be these: the wood, the weed, the wag.
The wood is that which makes the gallow tree;
The weed is that which strings the hangman's bag;
The wag, my pretty knave, betokeneth thee.
Mark well, dear boy, whilst these assemble not,
Green springs the tree, hemp grows, the wag is wild,
But when they meet, it makes the timber rot,
It frets the halter, and it chokes the child.
  Then bless thee, and beware, and let us pray
  We part not with thee at this meeting day.
