'Atonement Cover' in the Bible

And Yahweh said to Moses, "Tell your brother Aaron [that] he should not enter at any time into the sanctuary {behind} the curtain {in front of} the atonement cover that [is] on the ark, so that he might not die, because I appear in the cloud over the atonement cover.

and he shall put the incense on the fire {before} Yahweh so that the cloud of incense might cover the atonement cover, which [is] on the {covenant text}, so that he might not die.

And he shall take {some of} the bull's blood, and he shall spatter [it] with his finger on the atonement cover's surface on the eastern [side], and {before} the atonement cover he shall spatter {some of} the blood with his finger seven times.

"And he shall slaughter the sin offering's goat, which [is] for the people, and he shall bring its blood {from behind} the curtain, and he shall do with its blood as that which he did with the bull's blood, and he shall spatter it on the atonement cover and {before} the atonement cover.
