Leviticus 23:5-8

LEB(i) 5 In the first month, on the fourteenth of the month at the evening is Yahweh's Passover. 6 And on the fifteenth day of this month is Yahweh's Feast of Unleavened Bread; for seven days you shall eat unleavened bread. 7 On the first day there shall be a holy assembly for you; you shall not do any regular work.* 8 And you shall present an offering for Yahweh made by fire for seven days; on the seventh day there shall be a holy assembly; you shall not do any regular work.'"*
