Pleion (πλείων) is the comparative form of polys (G4183, much/many), meaning more, greater, or larger. It is used to express a greater quantity, quality, or degree when comparing two things.
Jesus uses pleion to establish His superiority over every Old Testament figure. In Matthew 12:41-42, He declares that something greater than Jonah and something greater than Solomon is here — referring to Himself. The comparative applied to Christ means He surpasses every prophet, king, and wise man. In Hebrews 3:3, Jesus has been found worthy of greater honor than Moses. In Luke 12:23, He reminds disciples that life is more than food. Paul notes in 1 Corinthians 15:6 that Christ appeared to more than 500 witnesses. The word consistently elevates the reader's gaze from lesser to greater — from temporal to eternal.
