'Fall Away' in the Bible

The earth shall be heavy and decay: The face of the earth shall perish and fall away, the proud people of the world shall come to naught.

And all the army of the heavens melted, and the heavens shall roll together as a book, and all their army shall fall away as the leaf falling from the vine, and as a falling from the fig tree.

Namely transgress and dissemble against the LORD, and fall away from our God: using presumptuous and traitorous imaginations, and casting false matters in our hearts.
