'Fail' in the Bible

For the Lord your God is a compassionate God; He will not fail you nor destroy you nor forget the covenant with your fathers which He swore to them.

Be strong and courageous, do not be afraid or tremble at them, for the Lord your God is the one who goes with you. He will not fail you or forsake you.”

The Lord is the one who goes ahead of you; He will be with you. He will not fail you or forsake you. Do not fear or be dismayed.”
