Translation: Scripture multiplies expressions of “burning” on the altar; all were expounded in Yoma concerning the number of wood-piles. “And he shall arrange the burnt-offering upon it” — the olah is first (Pesachim 58b).
On the daf / in context: The repeated language of perpetual fire is the source for the ma’arachot on the outer altar. The daily olah is arranged first upon that fire.
Middah: Custom (halakhic detail from redundant wording).
