הָקֵ֣ם לְ֭עַבְדְּךָ אִמְרָתֶ֑ךָ אֲ֝שֶׁ֗ר לְיִרְאָתֶֽךָ׃
Accomplis ton dire en faveur de ton serviteur, car [il amène] à te révérer.
Rashi on Psalms
Fulfill for Your servant Your word that You promised me.
Rashi on Psalms
that is for Your fear That I and my children shall fear Your name, for on that condition You promised me (I Kings 2:4): “if your children take heed in their way, etc.”
