Exodus 40:6

And thou shalt put the altar of burnt-offerings by the doors of the tabernacle of witness,

And you shall put the altar of burnt offerings by the doors of the tabernacle of witness, and you shall set up the tabernacle round about, and you shall hallow all that belongs to it round about.

And thou shalt set the altar of the burnt offering before the door of the tabernacle of the tent of the congregation.
