יִגְמְלֵ֣נִי יְהוָ֣ה כְּצִדְקִ֑י כְּבֹ֥ר יָ֝דַ֗י יָשִׁ֥יב לִֽי׃
L'Eterno mi ha ricompensato secondo la mia giustizia; secondo la pulizia delle mie mani mi ha ricompensato. .
Rashi on Psalms
according to my righteousness According to the righteousness of my following Him in the desert.
Rashi on Psalms
according to the cleanness Heb. כבד, an expression of cleanness, as (below 24:4), “and pure of heart.” Another explanation: He sent forth from on high [and] He took me. [David] said this about himself, concerning the angel who came to the Rock of the Divisions (I Sam. 23:27) to turn Saul away from him, as it is stated: “And an angel came to Saul, etc.”
Rashi on Psalms
according to my righteousness that I did not slay him when I sliced off the skirt of his coat. [Obviously, Rashi explains verses 8-17 as referring to Israel’s departure from Egypt. Only in verse 17 does he suggest the explanation that David refers to his own experiences.]
