Midrash su Salmi 18:26

And he gave unto Moses when he had made an end of speaking (Exod. 31:18). Scripture states with reference to this verse: A man’s gift maketh room for him, and bringeth him before great men (Prov. 18:16). The gift a man gives out of his own possessions resounds to his advantage, as is told about Abun Ramaah,²⁰See Deut. R. chapter 4, sect. 8, where he is called Abin the deceiver, not deceitful, simply cunning in giving charity. who resided in Bozrah.²¹An Idumean town in which a number of scholars lived. Our rabbis went there to obtain a contribution from him. However, he refused to contribute anything at all until all the men of the community had made their contributions. Then he contributed an amount equal to all the others. That is why he was called Abun, the deceiver. What did our rabbis do after that? They sat him amongst themselves to fulfill what is written: A man’s gift maketh room for him. Another explanation of And He gave unto Moses is contained in the verse: Thou hast also given me Thy shield of salvation, and Thy right hand hath holden me up; and Thy condescension hath made me great (Ps. 18:26). Thou hast given me Thy shield of salvation refers to the Israelites, who trust in the Holy One, blessed be He; Thy right hand hath holden me up alludes to the Torah, as it says: At His right hand a fiery law unto them (Deut. 33:2); And Thy condescension hath made me great relates to the condescension of the Holy One, blessed be He.
