'Failing' in the Bible

“Be careful that you don’t forget the Lord your God by failing to keep His command—the ordinances and statutes—I am giving you today.

You will find no peace among those nations, and there will be no resting place for the sole of your foot. There the Lord will give you a trembling heart, failing eyes, and a despondent spirit.

For both of you broke faith with Me among the Israelites at the waters of Meribath-kadesh in the Wilderness of Zin by failing to treat Me as holy in their presence.
