Chasidut zu Schir haSchirim 5:8

We find in the Talmud “From where do we know that a priest with a physical defect is invalid.? As it says ‘Behold I give him my covenant of peace (/SHaLOM/)’, when is he whole/complete (/SHaLeM/) therefore and not lacking. This is problematic however for SHaloM is written, with a VaV (and therefore does not have the meaning of complete/whole). But the Vav is severed (and therefore it may be read as having the meaning complete/whole). Elsewhere the Talmud explains the verse from Psalms “Pinchas stood in reckoning (VaYiPaLeL). VaYiTPaLeL (prayer) is not written, rather VaYiPaLeL (entreaty), to teach that he made a ׳reckoning׳ )(PeLiLaH) with his Creator.
