«وَالْحُرُّ يَجْزِي، وَالْإِلْطَاطُ يُخْزِي»
A noble free person repays kindness; obstinate insistence disgraces.

The two halves resemble earlier ethical antitheses. Their matched sound gives the petition fluency, while their difference in meaning presses the addressee toward the socially approved role of generous benefactor.
