Matthew 27:57

When even was come. The Hebrews reckoned two evenings, an earlier and a later. The former began midway between noon and sunset, or at three o'clock in the afternoon. The latter began at sunset, six o'clock. The reference here is to the earlier evening, though the time may have been well on toward the beginning of the later. The preparations had to be hurried because the Sabbath would begin at sunset.
