6 Moses and Aaron were among his priests, Samuel also was among those who called on his name. They cried to the Lord, and he answered them. 7 He spoke to them in the pillar of cloud; they kept his decrees, and the statutes that he gave them. 8 O Lord our God, you answered them; you were a forgiving God to them, but an avenger of their wrongdoings. 9 Extol the Lord our God, and worship at his holy mountain; for the Lord our God is holy.

Matthew Henry's Commentary on Psalm 99:6-9

Commentary on Psalm 99:6-9

(Read Psalm 99:6-9)

The happiness of Israel is made out by referring to the most useful governors of that people. They in every thing made God's word and law their rule, knowing that they could not else expect that their prayers should be answered. They all wonderfully prevailed with God in prayer; miracles were wrought at their request. They pleaded for the people, and obtained answers of peace. Our Prophet and High Priest, of infinitely greater dignity than Moses, Aaron, or Samuel, has received and declared to us the will of the Father. Let us not only exalt the Lord with our lips, but give him the throne in our heart; and while we worship him upon his mercy-seat, let us never forget that he is holy.
