Psalms 99:6 - Ellicott's Commentary On The Whole Bible

Moses. — Better, a Moses and an Aaron among his friends, and a Samuel among them that call upon his name; calling upon the Lord, and he answers them; in the pillar of cloud he speaks unto them. The poet is enhancing the sacred character of the services of his own day by likening the priests and ministers to the sacred heroes of the past, as we might distinguish a period of great scientific achievement by saying, “We have a Newton or a Bacon among us.” To make it a mere historical reference, “Moses and Aaron were,” &c, would be altogether too abrupt and inaccurate, since Moses was not a khohen, nor did God speak to Samuel in the cloudy pillar. It is true that the present tense is changed in Psalms 99:7 to the preterite, but it is quite natural that the psalmist should glide into the narrative style after the mention of the historical name. The Son of Sirach also makes special reference to the prayer of Samuel (Sir. 46:16). Possibly, too, there is an allusion to the meaning of his name, “asked,” or “heard of God.”
