Hebrews 12:5-6, 10

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; For whom the LORD loves He chastens, And scourges every son whom He receives.”

For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness.
