evening: the close of the day, from sunset into the early dark.
This is the ordinary Hebrew word for evening, the stretch of time as the sun goes down and the day ends. It marks one boundary of the daylight period, so it constantly pairs with morning to frame a whole day, and in the creation account each day is measured from evening to morning. Because the Israelite day turned over at sunset, evening was also where a new day began, which is why so many laws about cleanness reach their release point at evening.
The word covers the ordinary rhythms of life: when work stops, when people draw water, when travelers seek shelter, when an army or a sick man longs for the day to be over. It can also slide toward dusk and gathering darkness, the dim light at the edge of night.
One fixed use stands out from the rest. In the worship laws a special doubled form, often translated "between the two evenings," sets the exact time for the Passover lamb, the regular evening sacrifice, and the lighting of the lamps. Jewish tradition has long disagreed about precisely when that window falls, but it always names a definite point late in the day, not evening in general.
