(Hebrew: aman, strengthen) A word in scriptural and liturgical use, meaning "so be it." It is used as an acclamation which indicates that the speaker adopts for his own what has been said by another (Deuteronomy 27), as an affirmation of the speaker's own thought, and as a formula of conclusion at the end of prayers. It was often spoken by Our Lord, and is given as one of His names (Apocalypse 3:14).
