Psalms 12:3

¹ Help, O LORD, for the godly are no more; the faithful have vanished from among men.

² They lie to one another; they speak with flattering lips and a double heart.

May the LORD cut off all flattering lips and every boastful tongue.

⁴ They 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.”

Do read the surrounding verses too, because the context often says more than a single verse.
