What does Judges 10:6 mean?
The overall pattern of the book of Judges now begins again (Judges 2:11–19). Tragically, each circle brings the nation lower into sin, their deliverer is less virtuous, and their rescue is less secure. This time, the people not only turn to a particular god or idols of Canaan, but they also apparently embrace all of them at once.The list of false deities God's people served in this era includes familiar titles such as "the Baals" and "the Ashtaroth" (Judges 3:7; 8:33). This time, though, the Israelites add to their worship pantheon the gods of Syria, Sidon, Moab, the Ammonites (Genesis 19:36–38; Judges 3:13), and the Philistines (Genesis 10:13–14; Exodus 13:17). This means the people fully integrated themselves into all the worship practices of their friends and neighbors in Canaan.
To follow any god but the One True God already means abandoning His truth and His will (Exodus 20:1–6). Adding idols to one's religion is incompatible with faith in the God of Israel. Even if Israel tried to maintain worship of the Lord in addition to their idolatry, it would still be an abandonment of Him. For all practical purposes, the people of Israel entirely exchanged their worship of God for worship of idols.
As with the other times Israel fell into evil, it's natural to ask, "Why would they do this again?" In part, they probably hoped the gods of Canaan might do something for them which they believed the God of Israel could not or would not do. Further, they wanted to be like the people of Canaan. They wanted to fit in with their surrounding culture and to participate in the lifestyle of the people around them. In this case, integration included all the sexually immoral and violent practices that came with the worship of demonic false gods (Deuteronomy 12:29–31; 18:9–14).
