The two set of lines that show enjambment are (in bold):
"My heart leaps up when I behold
A rainbow in the sky:
So was it when my life began;
So is it now I am a man;
So be it when I shall grow old,
Or let me die!
The Child is father of the Man;
And I could wish my days to be
Bound each to each by natural piety."
Enjambment will be shown in a poem in lines that had no punctuation, that roll over from one to another with no terminating mark, it is used for pacing rhythm and for passing ideas.
