Psalms 99:6

He presseth them to perform the duty of praising and worshipping God by the examples of three eminent persons who practised this duty, and that with happy success. He reckoneth Moses among the priests not without cause, partly because before the institution of the priesthood he executed that office, Exodus 24:6 Num 7; and partly because he oft interceded to God for the people; which was a very considerable part of the priest's work. See Numbers 6:23, &c.; Joel 2:17. That call upon his name; who used frequently and solemnly to intercede with God on the behalf of the people. So the general expression is here used synecdoehically for this particular kind of prayer; such synecdoches being very frequent in Scripture. He answered them; Moses, Exo 32, and elsewhere; Aaron, Num 16, 1 Samuel 7:9, 1 Samuel 12:19: compare Jeremiah 15:1.
