This adjective means opportune, well-timed, or seasonable—the right time for something. In Mark 6:21, Herodias found 'an opportune day' when Herod gave a banquet for his nobles—the perfect occasion to manipulate him into executing John the Baptist. In Hebrews 4:16, believers may approach God's throne to receive mercy and find grace 'to help in time of need' (literally, for well-timed help)—grace arriving at just the right moment. The Spanish 'oportuno' and French 'convenable' (suitable, fitting) both convey appropriate timing. Classical usage emphasized seasonable rain, well-timed words, and convenient locations.
