What does Isaiah 9:15 mean?
Isaiah is describing the sudden loss of all of Israel's leadership (Isaiah 9:14). The Lord has caused this to happen because the people of Israel still would not turn to Him for help (Isaiah 9:13). This is after the previous judgment of destruction by other nations. Because the leaders of the northern ten tribes of Israel did not direct the people to seek the Lord and His help, those leaders are suddenly and irreversibly wiped out.These leaders include both "head and tail," Isaiah states (Isaiah 9:14). The head are the honored elders who appear to deserve attention and respect, though they do not. The tail are the false prophets who have been telling those leaders whatever they want to hear to keep their own positions and power. They will claim messages from the Lord or from false gods. The Lord will cut them all off at once, leaving Israel leaderless and vulnerable to attack.
