(Greek and Latin, hora.)
At the eleventh hour. Just in time not to be too late; only just in time to obtain some benefit. The allusion is to the parable of labourers hired for the vineyard (Matt. xx.).
My hour is not yet come. The time of my death is not yet fully come. The allusion is to the belief that the hour of our birth and death is appointed and fixed.
“When Jesus knew that His hour was come.”
John xiii. 1.

To keep good hours. To return home early every night; to go to bed bedtimes. “Se retirer la nuit de bonne heure.” In Latin, “Tempestive se domum recipere.”
