Unleavened Bread; the Feast of Unleavened Bread
Archimandrite Nikifor’s Biblical Encyclopedia
(Ex. 12:15; Lev. 23:5, 14; Num. 28:16, 25; Deut. 16:3–8 and elsewhere). Unleavened bread is bread made without leaven. The Feast of Unleavened Bread began on the second day of Passover and continued together with Passover for seven days. During that time, when sacrifices were offered in the sanctuary, the Hebrews were to possess and eat nothing leavened, under penalty of being cut off from Israel (Ex. 12:15–19). The first and last days of the feast were especially honored and marked by general assemblies in the court of the Tabernacle (Lev. 23:7–8).
