'Even' in the Bible

Boaz then addressed Ruth: "Listen, my daughter! Don't glean in any other field. Don't even leave this one, and be sure to stay close to my women servants.

She responded, "May I continue to find favor in your sight, sir, since you've been comforting me and you have spoken graciously to your servant, even though I am not one of your servants."

It's true that I'm your related redeemer, but there is another related redeemer even closer than I.
