God is without spot or moral blemish and is perfect in every aspect of Being. He is Just. He is Judge. He is never wrong.
Covenants are legal documents, legal oaths of faithfulness between parties.
When God makes a covenant, every covenant is founded on and written within His Perfect moral nature. God is wholly and completely Holy . The LORD abhors the man of bloodshed and deceit. The Bible always deals with the real. The person who murders is a murderer and God cannot love an unrepentant murderer.
