Hebrews 12:3-6

For consider him that hath endured such gainsaying of sinners against himself, that ye wax not weary, fainting in your souls. Ye have not yet resisted unto blood, striving against sin: and ye have forgotten the exhortation which reasoneth with you as with sons, My son, regard not lightly the chastening of the Lord, Nor faint when thou art reproved of him; For whom the Lord loveth he chasteneth, And scourgeth every son whom he receiveth.
