the Oak of Moreh: This was probably a Canaanite shrine. Fertile groves were sacred to the Canaanites (compare Isaiah 1:29), and Moreh means "teacher."
Abram proclaimed the Lord's name beside a pagan place of worship and instruction (Genesis 12:8).
Abram continued to be a blessing by building an altar to worship God at Shechem and east of Bethel (12:8).
