Hebrews 10:20 Since you died with Christ to the elemental spiritual forces of this world, why, as though you still belonged to the world, do you submit to its rules: 21“Do not handle! Do not taste!

"my laws" refers to the Paraclete or Holy Spirit of God. The putting is fulfilled when the Spirit/Paraclete dwells in my conscience.16 This is the covenant that I will make with them after those days, declares the Lord: I will put my laws on their hearts, and write them on their minds.
Rom 7:

Galatians 5:6 But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter.

Study God's commandments daily. Grow in the Spirit. Let your conscience and the peace of the Paraclete guide you in your daily walk.one who pleads another's cause before a judge, a pleader, counsel for defense, legal assistant; an advocate.
