'Testimony' in the Bible
Appoint the Levites over the tabernacle of the testimony, all its furnishings, and everything in it. They are to transport the tabernacle and all its articles, take care of it, and camp around it.
The Levites are to camp around the tabernacle of the testimony and watch over it, so that no wrath will fall on the Israelite community."
Whenever the camp is about to move on, Aaron and his sons are to go in, take down the screening veil, and cover the ark of the testimony with it.
When Moses entered the tent of meeting to speak with the Lord, he heard the voice speaking to him from above the mercy seat that was on the ark of the testimony, from between the two cherubim. He spoke to him [that way].
On the day the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony, and it appeared like fire above the tabernacle from evening until morning.
During the second year, in the second month on the twentieth [day] of the month, the cloud was lifted up above the tabernacle of the testimony.
Then place them in the tent of meeting in front of the testimony where I meet with you.
The next day Moses entered the tent of the testimony and saw that Aaron's staff, representing the house of Levi, had sprouted, formed buds, blossomed, and produced almonds!
The Lord told Moses, "Put Aaron's rod back in front of the testimony to be kept as a sign for the rebels, so that you may put an end to their complaints before Me, or else they will die."
But also bring your brothers with you from the tribe of Levi, your ancestral tribe, so they may join you and serve with you and your sons in front of the tent of the testimony.
