'Meaningless' in the Bible

Who cause a person to be indicted by a word,And ensnare him who adjudicates at the gate,And defraud the one in the right with meaningless arguments.

All the nations are as nothing before Him,They are regarded by Him as less than nothing and meaningless.

He it is who reduces rulers to nothing,Who makes the judges of the earth meaningless.

“And when you are praying, do not use meaningless repetition as the Gentiles do, for they suppose that they will be heard for their many words.
