New King James Version (NKJV)
5 And you have forgotten the exhortation which speaks to you as to sons:
“My son, do not despise the chastening of the Lord,
Nor be discouraged when you are rebuked by Him;
6 For whom the Lord loves He chastens,
And scourges every son whom He receives.”
7 If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten?
