Exodus 27:21
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
In the tabernacle of the congregation without the vail, which is before the testimony, Aaron and his sons shall order it from evening to morning before the Lord: it shall be a statute for ever unto their generations on the behalf of the children of Israel.
In the Tent of Meeting, outside the veil that is in front of the Testimony (note: The Testimony refers to the stone tablets in the ark of the covenant inscribed with the Ten Commandments.), Aaron and his sons are to tend the lamps before the LORD from evening until morning. This is to be a permanent statute for the Israelites for the generations to come.
