Charles H. Spurgeon on Psalms 20:6

"Now know I." A sudden change of number, speaking in the person of one, thereby to note the unity and consent of the people to this prayer, as though they had been all one, and uttered it all with one mouth. "The Lord will help his anointed;" that is, his king, whom he hath established. See Psalm 2:2; 18:50. "And will hear him (see verse 1), from his sanctuary." One readeth it thus —"from the heavens of his holiness;" meaning, from heaven where his holiness dwelleth. —Thomas Wilcocks.
