«رَاحْ يُخْطُبْهَا لُهْ اِجَّوِّزْهَا»

The picture is of a man sent to seek a woman's hand for someone else who ends up marrying her himself. The courtship scene is only a frame: service as a trusted go-between turns into taking the very prize he was meant to secure for another.

More broadly, it condemns a base person who is asked to help with some matter and then grabs the benefit for himself. Aimed at a real person, it accuses them of base betrayal, not mere luck or rivalry, through the contrast between the helping role accepted and the selfish outcome arranged.

Say it, with a sardonic edge, when any intermediary trusted to act for another, such as negotiating or seeking a favor, hijacks the outcome for personal gain. Applied to someone, it is a serious charge of betrayal; it also warns about choosing intermediaries.
