The ark of the covenant holds the 10 commandments written in stone by the finger of God
Deuteronomy 10:1-5.
Those first 10 are the Old Covenant written in stone and also the new covenant written on the fleshly tablets of the heart.
Deuteronomy 4:13
13 And he declared to you his covenant, which he commanded you to perform, that is, the Ten Commandments,and he wrote them on two tablets of stone.
Hebrews 8:10
10 For this is the covenant that I will make with the house of Israel
after those days, declares the Lord:
I will put my laws into their minds,
and write them on their hearts,
and I will be their God,
and they shall be my people.
Statutes and Ordinances (
Deuteronomy 4:44-28:68)
The rest of the commandments are statutes and ordinances some of which are either fulfilled in Christ (sacrificial law) or have spiritual application for us today.
Deuteronomy 22:5 for example is a part of the statutes and ordinances which have spiritual application for us today.
