'Heart is Faint' in the Bible

Why should you be stricken and punished again [since no change results from it]?You [only] continue to rebel.The whole head is sickAnd the whole heart is faint and sick.

“Let all their wickedness come before You;And deal with them as You have dealt with meBecause of all my transgressions;For my groans are many and my heart is faint.”
