Hebrews 12:11-13

11But no chastening at the time seems to be [matter] of joy, but of grief; but afterwards yields [the] peaceful fruit of righteousness to those exercised by it.

12Wherefore lift up the hands that hang down, and the failing knees;

13and make straight paths for your feet, that that which is lame be not turned aside; but that rather it may be healed.
