'Inside the Veil' in the Bible

Then he must take a firepan full of fiery coals from the altar before the Lord and two handfuls of finely ground fragrant incense, and bring them inside the veil.

“When he slaughters the male goat for the people’s sin offering and brings its blood inside the veil, he must do the same with its blood as he did with the bull’s blood: he is to sprinkle it against the mercy seat and in front of it.
