Deuteronomy 16:4; Deuteronomy 16:6; Deuteronomy 23:11; Deuteronomy 28:67

4 "For seven days no leaven shall be seen with you in all your territory, and none of the flesh which you sacrifice on the evening of the first day shall remain overnight until morning.

6 but at the place where the LORD your God chooses to establish His name, you shall sacrifice the Passover in the evening at sunset , at the time that you came out of Egypt.

11 "But it shall be when evening approaches, he shall bathe himself with water, and at sundown he may reenter the camp.

67 "In the morning you shall say, 'Would that it were evening!' And at evening you shall say, 'Would that it were morning!' because of the dread of your heart which you dread, and for the sight of your eyes which you will see.
