Exodus 30:6

And you shall put it in front of the veil that is above the ark of the testimony , in front of the mercy seat that is above the testimony , where I will meet with you.

Put the altar in front of the curtain that shields the ark of the covenant law—before the atonement cover that is over the tablets of the covenant law—where I will meet with you.

And thou shalt put it before the vail that is by the ark of the testimony, before the mercy seat that is over the testimony, where I will meet with thee.
