MLV(i)
5 And you have forgotten the encouragement which reasons with you as with sons, ‘My son, do not regard-lightly the disciplining of the Lord, nor be fainting when you are reproved by him.
6 For whom the Lord loves, he disciplines, and scourges every son whom he is accepting.’
7 It is for disciplining that you endure; God is dealing with you as with sons; for what is the son whom his father is not disciplining?
8 But if you are without discipline, of which all have become partakers, consequently, you are illegitimate and not sons.
