Final answer:
Abraham obeyed God by faith as stated in Hebrews 11:8, and he originated from Mesopotamia. This act of faith led to the establishment of the Covenant between God (Yahweh) and the Hebrew people.
Step-by-step explanation:
According to Hebrews 11:8, Abraham obeyed God by faith. This act of obedience led him to leave his homeland and journey to a place that he would later receive as an inheritance, though he did not know where he was going. Obeying through faith is a central theme in the narrative of Abraham's life.
As for where Abraham originally came from, according to the Hebrew Bible, Abraham hailed from Mesopotamia. His journey began in a place called Ur of the Chaldeans, which was located in the region of Mesopotamia, and from there, he moved as directed by his faith in God's promises. The Covenant between God, referred to in the question as Yahweh, and the Hebrew people is of significant religious importance. It established a relationship based on faith and obedience, with a promise for a prosperous land.
