This verb means to become sober or sober up—to recover from a drunken state, or metaphorically to come to one's senses and think clearly. In 1 Corinthians 15:34, Paul commands 'Become sober righteously and stop sinning.' While it can mean literal recovery from drunkenness, here it's metaphorical: wake up spiritually, think clearly. Classical usage confirms sleeping off drunkenness or recovering from emotional states. The multilingual evidence (Spanish 'despertad' = wake up, French 'devenir sobre' = become sober, German 'nüchtern werden' = become sober) shows both literal sobriety and metaphorical awakening.
