Parashas Vayikra · Aliyah 2 · Passuk 15
Chabad.org — English translation + Rashi
Torah Temima points to Zevachim 65a (verified; melikah at the top of the altar, like hakatarah).
English: “And he shall pinch” — adjacent to “and he shall cause to smoke”; melikah is juxtaposed with burning: just as burning is at the top of the altar, so melikah is at the top of the altar.
Custom (juxtaposition of location).
The kohen performs melikah while standing so that the act is at the upper surface of the altar.
