'Apostasy' in the Bible

Your wickedness will be punished, and you will be corrected due to your acts of apostasy. Know and see that it's evil and bitter for you to forsake the LORD your God, but the fear of me is not in you," declares the Lord GOD of the Heavenly Armies.

Why has this people turned away? Why does Jerusalem continue in apostasy? They hold on to deceit and refuse to repent.

Therefore thus said Jehovah, Lo, I am casting thee from off the face of the ground; this year thou diest, for apostasy thou hast spoken concerning Jehovah.'

Therefore, thus said Jehovah, Lo, I am seeing after Shemaiah the Nehelamite, and after his seed, he hath none dwelling in the midst of this people, nor doth he look on the good that I am doing to My people -- an affirmation of Jehovah -- for apostasy he hath spoken against Jehovah.'
