Whole chapter discussed by Augustine of Hippo —
The Godly Are No More
For the choirmaster. According to Sheminith. A Psalm of David.
1Help, O LORD, for the godly are no more;
the faithful have vanished from among men.
2They lie to one another;
they speak with flattering lips and a double heart.
3May the LORD cut off all flattering lips
and every boastful tongue.
4They say, “With our tongues we will prevail.
We own our lips—who can be our master?”
5“For the cause of the oppressed
and for the groaning of the needy,
I will now arise,” says the LORD.
“I will bring safety to him who yearns.”
6The words of the LORD are flawless,
like silver refined in a furnace,
like gold purified sevenfold.
7You, O LORD, will keep us;
You will forever guard us from this generation.
8The wicked wander freely,
and vileness is exalted among men.
