Jeremiah 5:19

And it shall come to pass, when ye shall say, Wherefore doeth the Lord, our God, all these things unto us? when they finally reach the point that they make inquiry concerning the punishment striking them, then shall thou answer them, Like as ye have forsaken Me and served strange gods in your land, in idolatrous worship, so shall ye serve strangers in a land that is not yours. Cf Deuteronomy 28:47. This was the Lord's retribution, which repaid the idolatrous people in kind.
