Psalms 9:20

Put them in fear, O Lord -From this it is evident that the enemies of the psalmist were bold, daring, confident in their own strength, and in the belief that they would succeed. He prays, therefore, that these bold and daring invaders of the rights of others might be made to stand in awe, and to tremble before the great and terrible majesty of God; that they might thus have just views of themselves, and see how weak and feeble they were as compared with Him. That the nations may know -The nations particularly referred to in this psalm as arrayed against the writer.
