This adjective describes what is without measure or beyond limits. Paul uses it twice in 2 Corinthians 10, discussing his apostolic sphere. In verse 13, he refuses to boast εἰς τὰ ἄμετρα—beyond limits, but will confine his boasting to the sphere God assigned him. Verse 15 similarly disclaims boasting εἰς τὰ ἄμετρα—beyond measure—in others' labors. The classical background includes immensity, moral excess, and disproportion. Paul employs it to describe territorial overreach—claiming credit for work in areas God hasn't assigned him—maintaining proper boundaries in apostolic ministry and boasting.
