'Senseless' in the Bible

“Do you thus repay the Lord,O foolish and unwise people?Is not He your Father who has acquired you [as His own]?He has made you and established you [as a nation].

“Declare among the nations.Lift up a signal [to spread the news]—publish and proclaim it,Do not conceal it; say,‘Babylon has been taken,Bel [the patron god] has been shamed, Marduk (Bel) has been shattered.Babylon’s images have been shamed, her [worthless] idols have been thrown down.’

My people consult their [lifeless] wooden idol, and their [diviner’s] wand gives them oracles.For a spirit of prostitution has led them astray [morally and spiritually],And they have played the prostitute, withdrawing themselves from their God.
