'Senseless' in the Bible

They are but fools, the princes of Zoan, the wise counsellors of Pharaoh: their counsel is become senseless. How say ye unto Pharaoh, I am the son of the wise, the son of ancient kings?

Indeed, they will hear meaningless gibberish, senseless babbling, a syllable here, a syllable there.

So the Lord's word to them will sound like meaningless gibberish, senseless babbling, a syllable here, a syllable there. As a result, they will fall on their backsides when they try to walk, and be injured, ensnared, and captured.
