'Disappeared' in the Bible

For the choir director: according to Sheminith. A Davidic psalm.Help, Lord, for no faithful one remains;the loyal have disappeared from the human race.

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.
