'Backslider' in the Bible

The backslider in heart shall be filled with his own ways: and a good man shall be satisfied from himself.

In that day doth one take up for you a simile, And he hath wailed a wailing of woe, He hath said, We have been utterly spoiled, The portion of my people He doth change, How doth He move toward me! To the backslider our fields He apportioneth.
