'Disappeared' in the Bible

For the music director; according to the sheminith style; a psalm of David. Deliver, Lord! For the godly have disappeared; people of integrity have vanished.

But then one passes by, and suddenly they have disappeared! I looked for them, but they could not be found.

Has his loyal love disappeared forever? Has his promise failed forever?

They surrounded me like bees. But they disappeared as quickly as a fire among thorns. Indeed, in the name of the Lord I pushed them away.
