Analysis of To his verses

What will ye, my poor orphans, do,
When I must leave the world and you;
Who'll give ye then a sheltering shed,
Or credit ye, when I am dead?
Who'll let ye by their fire sit,
Although ye have a stock of wit,
Already coin'd to pay for it?
--I cannot tell:  unless there be
Some race of old humanity
Left, of the large heart and long hand,
Alive, as noble Westmorland;
Or gallant Newark; which brave two
May fost'ring fathers be to you.
If not, expect to be no less
Ill used, than babes left fatherless.
