Psalms 73:17

Until I went into the sanctuary of God -The word “sanctuary” we now apply to a place of public worship; and, thus understood, the passage here would mean that he learned the truth on the subject only by the statements and disclosures made there in regard to the divine plans and dealings, and the results of human conduct. This interpretation makes good sense, and is in itself true, but it is not the idea in the original. The word “sanctuary” in the Old Testament, in the singular number, is applied to the tabernacle, or the temple, or, more especially to the most holy place in the tabernacle or the temple; the place of the unique dwelling of God.
