This is the end of the Hallelujah Hymns and the end of the whole book. It serves honorably to hold that place as the capstone of worship.
Hallelujah! At the very least we should come to the Temple and praise Him. However, there is no place in His whole Creation where praise is out of place. Indeed, let all Creation praise Him together at once. Do you need a reason? Think of the powerful actions He has taken. Contemplate His greatness; you cannot fathom it.
Like a conductor, the psalmist calls first for the brass section to catch our attention with sharp notes. Then he brings up the stringed harps and lyres. He motions for dancers to begin their moves while the timbrels pop and jingle in their hands. Next, he signals to the woodwinds and other strings to raise their voices. Finally comes the crashing crescendo of various cymbals and grand gongs.
Were that not enough, let all breathing creatures raise their voice in earth-shattering praise. Yes, praise the Lord, indeed.
