'Senseless' in the Bible

Sons of senseless and nameless people, they were driven out of the land with whips.

I was ignorant and lacked insight; I was as senseless as an animal before you.

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.
