Abraham (formerly called Abram) is viewed as one of the most important persons if not the most important person in Scripture besides Yeshua Himself. YeHoVaH introduced Himself to Moses as the Elohim of Abraham, Isaac, and Israel/Jacob.  The faith we confess today started with the faith of Abraham.  In this passage, Abram was commanded to get out of his country, get away from his kindred, and get from his father's house.  Because Abraham was emotionally connected to his family, he brought with him his father, Terah, and nephew, Lot.  In spite of this, Abraham trusted YeHoVaH and YeHoVaH made several everlasting promises to Abraham in this passage.
