Psalms 101:5

³ I will set no worthless thing before my eyes. I hate the work of those who fall away; it shall not cling to me.

⁴ A perverse heart shall depart from me; I will know nothing of evil.

Whoever slanders his neighbor in secret, I will put to silence; the one with haughty eyes and a proud heart, I will not endure.

⁶ My eyes favor the faithful of the land, that they may dwell with me; he who walks in the way of integrity shall minister to me.

⁷ No one who practices deceit shall dwell in my house; no one who tells lies shall stand in my presence.

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