'Tabernacle of the Testimony' in the Bible

These are the things numbered of the tabernacle, the tabernacle of the testimony, which were counted, according to the commandment of Moses, by the service of the Levites, under the hand of Ithamar, son of Aaron the priest.

And it came to pass in the second year, in the second month, on the twentieth of the month, that the cloud was taken up from off the tabernacle of the testimony.
