Judges 4:1

“And the children of Israel again did evil in the sight of the Lord, etc.] Which was the fruit and effect of the long rest and peace they enjoyed; and which is often the case of a people favoured with peace, plenty, and prosperity, who are apt to abuse their mercies, and forget God, the author and giver of them; and the principal evil, though not expressed, was idolatry, worshipping Baalim, the gods of the nations about them; though it is highly probable they were guilty of other sins, which they indulged in the times of their peace and prosperity: when Ehud was dead; Shamgar is not mentioned, because his time of judging Israel was short, and the people were not reformed in his time, but fell…”
