'Fail' in the Bible

Cast your burden on the Lord [release it] and He will sustain and uphold you;He will never allow the righteous to be shaken (slip, fall, fail).

I am weary with my crying; my throat is parched;My eyes fail while I wait [with confident expectation] for my God.

Do not cast me off nor send me away in the time of old age;Do not abandon me when my strength fails and I am weak.

My flesh and my heart may fail,But God is the rock and strength of my heart and my portion forever.

“Nevertheless, I will not break off My lovingkindness from him,Nor allow My faithfulness to fail.

My eyes fail [with longing, watching] for [the fulfillment of] Your promise,Saying, “When will You comfort me?”

My eyes fail [with longing, watching] for [the fulfillment of] Your salvation,And for [the fulfillment of] Your righteous word.
