Leviticus 23:5-7

CAB(i) 5 In the first month, on the fourteenth day of the month, between the evening times is the Lord's Passover. 6 And on the fifteenth day of this month is the Feast of Unleavened Bread to the Lord; seven days shall you eat unleavened bread. 7 And the first day shall be a holy convocation to you: you shall do no customary work.
