'Fail' in the Bible

If the people avoid dealing with that man when he offers his child to Molech that is, if they fail to execute him

and if you refuse my statutes, loathe my ordinances, and fail to carry out all of my commands, thereby breaching my covenant,

then I will certainly do this to you: I'll appoint sudden terror to infect you like tuberculosis and fever. Your eyes will fail and your life will waste away. You'll plant in vain, because your enemies will consume what you plant.
