My son, keep thy father’s commandment, and forsake not the law of thy mother: bind them continually upon thine heart, and tie them about thy neck. When thou goest, it shall lead thee; when thou sleepest, it shall keep thee; and when thou awakest, it shall talk with thee. For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life: To keep thee from the evil woman, from the flattery of the tongue of a strange woman.  Lust not after her beauty in thine heart; neither let her take thee with her eyelids.

Proverbs 6:20-25

The commandment of the father,  and the law of the mother are compatible because they are equal in discipline, correction, and instruction.

The words are from a father to his son, and as the word of God is directed from God our heavenly Father to His  sons (children) of the new birth.  Note what the commandment, and the law do for those who will listen, hear and do it.

First it will give you peace when you sleep through the night.  It will talk to you when you are awake.

It does this for us; GOD does this for us to keep us from  evil.  God is full of love, mercy, and grace.  He will deliver  you when you turn from your sins to Him through Jesus Christ who bled and died on the cross, He was buried and He rose again.
