John Gill Commentary Proverbs 23:13

"Withhold not correction from the child; [For] if thou beat him with the rod, he will not die." — Proverbs 23:13 (ASV)

Withhold not correction from the child
When he has committed a fault, and correction is necessary; for to spare it is the ruin of the child, and no proof of true affection in the parent, but the reverse; see (Proverbs 13:24) (19:18) ; for, [if] you beat him with a rod, he will not die ;
if he is beaten moderately, there is no danger of his dying under the rod, or with the stripes given him; besides, such moderate and proper corrections may be a means of preserving him from such crimes as would bring him to a shameful and untimely death, and so he will not die such a death; and by such means, through the grace of God, he may escape the second, or eternal death.
