Traditionally, Moses was the writer of the first five books of The Bible, known collectively as the Pentateuch, or, The Torah. Exodus is the second book of the five. (The English phonetic spelling of the Hebrew name for Exodus is Sh'moat.) Thus, Moses is the writer of Exodus and that is how they link together.
The covenant with Moses is already made and most religions hold that you cannot intercede with the Dead for a new covenant.
Moses
The three major Jewish covenants are Noah's Covenant, Abraham's Covenant, the Mosaic Covenant (Moses' Covenant.)
that is the Ark of the Covenant. The Bible states that it is a sacred container wich houses the tablets of the 10 commandaments. For more information I posted in the related links box below the wikipedia article on the Ark of the Covenant.
Moses
It must be Moses and his brother Aaron.
In the Sinai Covenant, God made a covenant with the Israelites through Moses on Mount Sinai. The covenant included the giving of the Ten Commandments and other laws which the Israelites were to follow. It established rules for the Israelites to live by, and outlined the consequences for obedience and disobedience.
The Ark of the Covenant contained the two stone tablets with the Ten Commandments that God had given Moses.
The Ark of the Covenant stored the stone tablets inscribed with the Ten Commandments given to Moses by God.
According to Jewish chronology, it was made in 1312 BCE.
Moses
On Mount Sinai in Egypt, God created a covenant with the people of Israel by speaking to Moses, their leader. This occurred in Genesis chapter 34:10-28.
