The wicked return to the grave, all the
nations that forget God. But the needy
will not always be forgotten, nor the
hope of the afflicted ever perish.

Psalm 9:17,18

The justice which has punished the wicked, and preserved the righteous,
remains the same, and therefore in days to come, retribution will surely
be meted out. How solemn is the seventeenth verse, especially in its
warning to forgetters of God. The moral who are not devout, the honest
who are not prayerful, the benevolent who are not believing, the amiable
who are not converted, these must all have their portion with the openly
wicked in the hell which is prepared for the devil and his angels…

Arise, O Lord, let not man triumph;
let the nations be judged in your presence.
Strike them with terror, O Lord; let the
nations know they are but men.

Psalm 9:19,20

Prayers are the believer’s weapons of war. When the battle
is too hard for us, we call in our great ally, who, as it
were, lies in ambush until faith gives the signal by crying
out,

”Arise, O Lord.” Although our cause be all but lost, it
shall be soon won again if the Almighty doth but bestir himself.

He will not suffer man to prevail over God, but with swift
judgments will confound their gloryings. In the very sight
of God the wicked will be punished, and he who is now all
tenderness will have no bowels of compassion for them,
since they had no tears of repentance while their day of
grace endured.

Charles H. Spurgeon from Treasury of David Vol 1  p.100-101.
