Hebrews 12:4-6

41You have not yet resisted 23to the point of shedding blood in your striving against sin; 5and you have forgotten the exhortation which is addressed to you as sons, “4My son, do not regard lightly the discipline of the Lord, Nor 5faint when you are punished by Him;66For 7whom the Lord loves He disciplines, And He punishes every son whom He accepts.”
