Hebrews 12:4-7 New King James Version (NKJV)

4. You have not yet resisted to bloodshed, striving against sin.

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?
