Charles H. Spurgeon on Psalms 98:4

Make a joyful noise. Bless God for a Christ. The Argives when delivered by the Romans from the tyranny of the Macedonians and Spartans, Quae guadia, quae vociferationes fuerunt! quid florum in Consulem profuderunt! what great joys expressed they! what loud outcries made they! The very birds that flew over them fell to the ground, astonied at their noises. The crier at the Nemean games was forced to pronounce the word Liberty, iterumque, iterumque, again, and again. John Trapp.

Verses 4-6. Wherewith is God to be praised? In a literal sense with all kind of music: vocal, sing unto the Lord: chordal, Praise him upon the harp: pneumatical, with trumpets, etc. In an allegorical exposition (as Euthymius interprets it) we must praise God in our actions, and praise him in our contemplation; praise him in our words, praise him in our works; praise him in our life, praise him at our death; being not only temples (as Paul), but (as Clemens Alexaudrinus calls us) timbrels also of the Holy Ghost. John Boys.
