English: “He shall pour out” — to include the pouring of the remainders.
Pouring of the remainders — after the blood applications on the horns, the remaining blood is poured at the base of the outer altar.
After the blood applications on the horns, the remaining blood is poured at the base of the outer altar. The verse’s “he shall pour out” is understood to require the disposal of the residual blood at the designated foundation of the olah altar. This completes the blood service of the High Priest’s chatas by ensuring that no blood is left unused or improperly discarded.
