And though my Lord hath lost his estate and been banished out of his country, yet neither despised poverty nor pinching necessity could make him break the bonds of friendship or weaken his loyal duty.

This quote is talking about a person’s loyalty and friendship. This person’s lord has lost their estate and been removed from their country, so they have been going through financial hardship. Despite this, this person remains loyal and committed to their friends – they do not let poverty or any other difficult situation affect their loyalty or weaken their sense of duty.
