Numbers 3:38

They that encamp before the tabernacle of witness on the east [shall be] Moses and Aaron and his sons, keeping the charges of the sanctuary according to the charges of the children of Israel; and the stranger that touches them, shall die.

But those that encamp before the tabernacle toward the east, even before the tabernacle of the congregation eastward, shall be Moses, and Aaron and his sons, keeping the charge of the sanctuary for the charge of the children of Israel; and the stranger that cometh nigh shall be put to death.

Those who encamp before the tabernacle eastward, in front of the Tent of Meeting toward the sunrise, shall be Moses, with Aaron and his sons, keeping the requirements of the sanctuary for the duty of the children of Israel. The outsider who comes near shall be put to death.
