'Ceased' in the Bible

To the Overseer, on the octave. -- A Psalm of David. Save, Jehovah, for the saintly hath failed, For the stedfast have ceased From the sons of men:

And -- in my halting they have rejoiced, And have been gathered together, Gathered against me were the smiters, And I have not known, They have rent, and they have not ceased;

The words of his mouth are iniquity and deceit, He ceased to act prudently -- to do good.

And precious is the redemption of their soul, And it hath ceased -- to the age.

Hath His kindness ceased for ever? The saying failed to all generations?
