Matthew Poole and continuators on Hebrews 12:6

6 For whom the Lord loveth he chasteneth, and scourgeth every Son whom he receiveth.

Scourgeth, noteth the highest degree of Chastening, even with the sharpest and most smarting Punishment, wherein God proceedeth with all and every Son or Child, not any excepted, whom he hath Adopted and received into his Bosom with complacency and delight, chap. 5.8. compare Prov. 3.12. Matth. 17.5. Rev. 3.19. where though the Words do vary, yet the sense is one and the same; God correcting, as a Father, the Son in whom he delighteth.

For, sheweth this to be a suasory reason against fainting under God's rebukes, and enforcing the foregoing Duty; since whomsoever, Son or Daughter, every Child that God the Father choicely loveth, taketh into his Bosome, tendreth as a Parent doth a Child, Ephes, 5.1. He nurtureth, instructs, corrects by his Word and Rod in its respective measure, for their spiritual profit and advantage, 1 Cor. 11.32.
