Tafsiran Mazmur 6:4: Rashi & Radak

and You, O Lord, how long will You look on and not heal [me]?

And Thou (ואת), – written (Kethib) without he (ה), but to be read (Keri) with he (ה); but it is without significance, for it is found (written) without he; thus (for example): “And if Thou (אַתְּ) deal thus with me” (Num. 11:15).
