I am doing Shakespeare studying Much ado about nothing and do not understand what the following quotation means:

"Being reconciled to the prince your brother: I owe you all duty"

"Let us to the great supper, their cheer is greater that I am subdued. Would the cook were a my mind:shall we go prove what's to be done"

Now that you have made up with your brother, I owe you the same allegiance as your brother.
