Analysis of To death

Thou bidst me come away,
And I'll no longer stay,
Than for to shed some tears
For faults of former years;
And to repent some crimes
Done in the present times;
And next, to take a bit
Of bread, and wine with it;
To don my robes of love,
Fit for the place above;
To gird my loins about
With charity throughout;
And so to travel hence
With feet of innocence;
These done, I'll only cry,
'God, mercy!' and so die.
