Make a joyful noise unto the LORD, all the earth: make a loud noise, and rejoice, and sing praise.
-How Yahweh is to be praised by all the earth-namely, with all means in men's power-vocal and instrumental music.
Verse 4. Make a joyful noise unto the Lord, all the earth - (Psalms 66:1, written in the time of Hezekiah.) Yahweh here is substituted for 'Elohiym (H430) there. Also Psalms 47:1-2.
Make a loud noise, and rejoice - literally, 'break forth and be jubilant.' A favorite expression in the probably contemporary prophet Isaiah (Isaiah 14:7; Isaiah 44:23; Isaiah 49:13; Isaiah 54:1). Isaiah, however, may have at a later date drawn this expression, as well as others, from this group of psalms, which, from their similarity to Psalms 47:1-9 and Psalms 48:1-14, seem to belong to the same period-namely, the reign of Jehoshaphat, when the Lord gave such a blow to the confederate world-powers-a time in which praise-songs were the precursors of victory.
Verse 5. Sing - (Psalms 47:6.)
With ... the voice of a psalm - or, as the Hebrew is cognate to that for "sing," 'with the voice of a song' (Isaiah 51:3, "the voice of melody" or song): the same Hebrew as here х zimraah (H2172)], cognate to mizmowr (H4210), "a psalm" or song, in the title.
Verse 6. Before the Lord, the King - before Him who has now taken visibly to Him His power and kingdom over the whole earth (Isaiah 6:5; Psalms 97:1; Revelation 11:15; Revelation 11:17).
