John Gill Commentary Judges 2:17

"And yet they hearkened not unto their judges; for they played the harlot after other gods, and bowed themselves down unto them: they turned aside quickly out of the way wherein their fathers walked, obeying the commandments of Jehovah; [but] they did not so." — Judges 2:17 (ASV)

And yet they would not listen to their judges
Afterwards, or not always; but when they admonished them of their sins, and advised them to walk in the good ways of God, and serve him only; they turned a deaf ear to them, and went on in their own ways, which is a sad aggravation of their iniquities:

but they went a whoring after their gods, and bowed themselves to
them ;
committed spiritual adultery, for such idolatry is, and is often so represented in Scripture.

For by it they broke the covenant God made with them, which had the nature of a matrimonial contract, and in which God was a husband to them; and therefore serving other gods was rejecting him as such, and committing whoredom with others; than which nothing was more provoking to God, jealous of his honour and glory:

they turned quickly out of the way which their fathers walked in ;
as soon as Joshua and the elders were dead, they departed from the God of their fathers, and the way in which they worshipped him; and so likewise quickly after they had been delivered by the judges, or however as soon as they were dead:

obeying the commandments of the Lord ;
serving him at his tabernacle, according to the laws, commands, and ordinances he gave to Moses, which is to be understood of their fathers:

[but] they did not so ;
did not walk in the same way, nor serve the Lord, and obey his commands, as their fathers did; but all the reverse.
