'Tabernacle Of The Lord' in the Bible

Then tidings came to Joab: for Joab had turned after Adonijah, though he turned not after Absalom. And Joab fled unto the tabernacle of the LORD, and caught hold on the horns of the altar.

And it was told king Solomon that Joab was fled unto the tabernacle of the LORD; and, behold, he is by the altar. Then Solomon sent Benaiah the son of Jehoiada, saying, Go, strike him down.

And Benaiah came to the tabernacle of the LORD, and said unto him, Thus says the king, Come forth. And he said, Nay; but I will die here. And Benaiah brought the king word again, saying, Thus said Joab, and thus he answered me.
