Read Isaiah 57:10 Using Other Translations
Thou art wearied in the greatness of thy way; yet saidst thou not, There is no hope: thou hast found the life of thine hand; therefore thou wast not grieved.
You were wearied with the length of your way, but you did not say, "It is hopeless"; you found new life for your strength, and so you were not faint.
You grew weary in your search, but you never gave up. Desire gave you renewed strength, and you did not grow weary.
