At the beginning, Abraham was displayed as a nomad, a wanderer, who was chosen by God for His plans. Abraham didn't have any material property, but by the end of his life he was a rich man. All that he longed for became a reality. He was given more than he expected, based on his strong and unshakable faith. He made a covenant with God and altered his life completely. This paper is based on the literature that endeavors to approximate the climate surrounding Abraham and his family. The first part gives general information of the term covenant (heb. berit) and it's correlation with Hittite treaties. The second part focuses on Abraham's life before and after he was called by God and his faith as an answer. In the third part, the term covenant is depicted as a partnership, a friendly relation between God and man, a covenant forged by an unusual rite. It's important to mention the two traditions connected with this third part the Yahwist and the Elohist sources. The last chapter focuses on God's promises, the term circumcision and the modifications from the name Abram into Abraham.Abraham is one of the few persons that put faith in God even though he didn't know Him. He left his clan and departed with his wife Sarah on a path laid out by God. That path led him into the unknown, but Abraham was filled with certainty because beside Sarah, he had another companion by his side God. He made a covenant with God and became His everlasting friend.
