In Ben's message from Judges this morning (2/28/10) he pointed out an interesting parallel between the place of Joshua's last speech and Abimelech's coronation in Judges 9:6 "And all the men of Shechem gathered together, all of Beth Millo, and they went and made Abimelech king beside the terebinth tree at the pillar that was in Shechem." Warren Wiersbe gives us a few additonal interesting details.
"This is probably the “oak of Moreh,” where the Lord appeared to Abraham and promised to give him and his descendants the land (Gen. 12:6). It was near this site that the nation of Israel heard the blessings and curses read from the Law and promised to obey the Lord (Deut. 11:26–32; Josh. 8:30–35). Jacob buried the idols here as he called his family back to God (Gen. 35:1–5), and here Joshua gave his last speech and led the people in reaffirming their obedience to the Lord (Josh. 24:25–26). All of this sacred history was degraded and dishonored by the selfish acts of one godless man." Be Available, An Old testament study. (Wheaton, IL: Victor Books, 1996), 82.
