אַֽל־תִּגְּעוּ֙ בִּמְשִׁיחָ֔י וּבִנְבִיאַ֖י אַל־תָּרֵֽעוּ׃ (פ)
"Ne touchez pas à mes oints, Ne faites pas de mal à mes prophètes!"
Rashi
למשחה means to be raised to dignity by means of them. For sometimes the word משח is used in the sense of “dignity”, as in (Numbers 18:8), “to thee I have given them as a dignity (למשחה)”, and (I Chronicles 16:22) “Touch ye not my nobles (משיחי)” (cf. Rashi on Exodus 30:29).
