Our reading
An editorial interpretation.
The speaker invites an unspecified action to continue indefinitely, while addressing the other person as 'my Lord'. The open-ended permission conveys strong approval or willingness. Its intimacy and deference are present in the wording, but the action itself is left for context to supply.
