Tell her that she has some connection to me through your burning (or suffering), or don't make any claims for my sake if you bring nothing.

This powerful couplet captures the pain of being misunderstood and undervalued. The speaker is addressing a third party who is speaking about him to the beloved. He pleads for at least some truthful mention of his worth. Yet, he simultaneously confronts that person, accusing them of making hollow boasts and claims without any genuine action or effort. It's a poignant mix of desperate longing and sharp self-respect.
