'Weakening' in the Bible

Then [the leaders of] Judah said,“The strength of the burden bearers is failing,And there is much rubble;We ourselves are unableTo rebuild the wall.”

This made the Jews more determined than ever to kill Him, for not only was He breaking the Sabbath [from their viewpoint], but He was also calling God His own Father, making Himself equal with God.

Love bears all things [regardless of what comes], believes all things [looking for the best in each one], hopes all things [remaining steadfast during difficult times], endures all things [without weakening].

And as for [the rest of] you, believers, do not grow tired or lose heart in doing good [but continue doing what is right without weakening].
