God's Ten Commandments were inscribed on two tablets of stone by His own finger, and they are called "covenant" or "testimony."
God wrote the Ten Commandments using His own finger. This list of 10 commandments declares His sovereign will for mankind. He wants all mankind to observe them willfully.
God deliberately kept His law out of sight because His law has value only if it is written on the tablets of our heart. (Hebrews 8:10) God knew that mankind would view the Ten Commandments as an external icon rather than the embodiment of truth.
