Leviticus 23:5-8

Leeser(i) 5 On the fourteenth day of the first month, toward evening, is the passover-lamb to be offered unto the Lord. 6 And on the fifteenth day of the same month is the feast of unleavened bread unto the Lord: seven days must ye eat unleavened bread. 7 On the first day there shall be a holy convocation unto you; no servile work shall ye do thereon. 8 And ye shall offer an offering made by fire unto the Lord seven days: on the seventh day is a holy convocation; no servile work shall ye do.
