Fathers, do not exasperate your children, that they may not lose heart….Do not provoke your children to anger; but bring them up in the discipline and instruction of the Lord. (Col 3:21, Eph 6:4).
[For] he who spares his rod hates his son, but he who loves him disciplines him diligently….Do not hold back discipline from the child, although you beat him with the rod, he will not die. You shall beat him with the rod and deliver his soul from Sheol. (Prov 13:24, 23:13-14).
These words which I am commanding you today shall be on your heart; and you shall teach them diligently to your sons and shall talk of them when you sit in your house and when you walk by the way and when you lie down and when you rise up….Take to your heart all the words with which I am warning you today, which you shall command your sons to observe carefully, even all the words of this law. For it is not an idle word for you; indeed it is your life. And by this word you shall prolong your days in the land. (Deuteronomy 6:6-7, 32:46-47).
