Ye that stand in the house of the Lord - See the notes at Psalm 134:1. That is, those who were appointed to conduct the services of religion, the priests and Levites.
In the courts of the house of our God - The areas, or parts assigned for different classes of worshippers around the tabernacle and the temple. See the notes at Matthew 21:12; notes at Psalm 92:13.

Ye that stand - Priests and Levites. For which he gives several reasons.

Ye that (a) stand in the house of the LORD, in the (b) courts of the house of our God,
(a) You Levites who are in his sanctuary.
(b) Meaning, the people: for the people and Levites had their courts, which were separate places of the temple.

Ye that stand in the house of the Lord,.... That have a place and standing there, and go not out, being sons as well as servants; See Gill on Psalm 134:1 and See Gill on Psalm 84:4;
in the courts of the house of our God; alluding to the courts in the temple, the court of the priests, where they stood and ministered, slaying and offering their sacrifices; and the great court, where all the Israelites stood and worshipped, 2-Chronicles 4:9. So this may describe the worshippers of God in common, who should praise him: and happy are they that have a place here; see Psalm 84:1.

Ye - Ye priest and Levites.
