'Evening' in the Bible

No yeast shall be seen with you in all your borders seven days; neither shall any of the flesh, which you sacrifice the first day at evening, remain all night until the morning.

but at the place which Yahweh your God shall choose, to cause his name to dwell in, there you shall sacrifice the Passover at evening, at the going down of the sun, at the season that you came forth out of Egypt.

but it shall be, when evening comes on, he shall bathe himself in water; and when the sun is down, he shall come within the camp.

In the morning you shall say, "I wish it were evening!" and at evening you shall say, "I wish it were morning!" for the fear of your heart which you shall fear, and for the sight of your eyes which you shall see.
