Hebrews 12:5

“And ye have forgotten the exhortation, etc..] Or consolation, the consolatory word or doctrine, in (<200311>Proverbs 3:11). This, by their conduct, the apostle feared they had forgotten, and therefore puts them in mind of it; or it may be read by way of question, “and have ye forgotten?”, etc.. do not ye remember? it would be right to call it to mind: which speaketh unto you as unto children; not as the children of Solomon, but as the children of God, or of Christ, the wisdom of God: here, by a prosopopeia, the word of exhortation is introduced as a person speaking, my son, despise not thou the chastening of the Lord; by which is meant, not vindictive punishment; this would not be speaking…”

“forgotten--"utterly," so the Greek. Compare Heb 12:15-17, in which he implies how utterly some of them had forgotten God's word. His exhortation ought to have more effect on you than the cheers and exhortations of the spectators have on the competitors striving in the games. which--Greek, "the which," of which the following is a specimen [ALFORD]. speaketh unto you--as in a dialogue or discourse, so the Greek, implying God's loving condescension (compare Isa 1:18). despise not--literally, "Do not hold of little account." Betraying a contumacious spirit of unbelief (Heb 3:12), as "faint" implies a broken-down, weak, and desponding spirit. "Chastening" is to be borne with "subjection" (Heb…”

“And ye have forgotten the exhortation - This exhortation is found in Proverbs 3:11-12. The object of the apostle in introducing it here is, to show that afflictions were designed on the part of God to produce some happy effects in the lives of his people, and that they ought, therefore, to bear them patiently. In the previous verses, he directs them to the example of the Saviour. In this verse and the following, for the same object he directs their attention to the design of trials, showing that they are necessary to our welfare, and that they are in fact proof of the paternal care of God. This verse might be rendered as a question. “And have ye forgotten?” etc. This mode of rendering it…”

“And yet ye seem already to have forgotten the exhortation - Wherein God speaketh to you with the utmost tenderness. Despise not thou the chastening of the Lord - Do not slight or make little of it; do not impute any affliction to chance or second causes but see and revere the hand of God in it. Neither faint when thou art rebuked of him - But endure it patiently and fruitfully. Pro 3:11, &c. Hebrews 12:6”

“12:5-6 In these verses, the encouraging words are quoted from Prov 3:11-12, a passage that regards hardship as the Lord’s loving discipline for his children. God can turn a wide variety of trials and difficulties to our good, training us in righteousness and holy character.”
