'Tabernacle of the Testimony' in the Bible

but appoint the Levites over the Tabernacle of the Testimony, and over all its furnishings, and over all that belongs to it. They shall carry the tabernacle, and all its furnishings; and they shall take care of it, and shall encamp around it.

But the Levites shall encamp around the Tabernacle of the Testimony, that there may be no wrath on the congregation of the children of Israel: and the Levites shall be responsible for the Tabernacle of the Testimony."

It happened in the second year, in the second month, on the twentieth day of the month, that the cloud was taken up from over the tabernacle of the testimony.
