No leavened bread. Leavened bread was prohibited with any meal offering (see on Lev. 2:1), inasmuch as leaven represents fermentation and decay, and hence corruption.
Seven days. See Ex. 12:15, 18-20; 13:6, 7; 23:15; Lev. 23:6.
Affliction. The word thus translated is from a root meaning “to be bowed down,” “to be frustrated.” The reference here is to the servitude of Israel in Egypt (Ex. 3:7; 4:31).
In haste. The expression thus translated is from a word meaning “to be alarmed,” “to be in trepidation.” The corresponding Arabic verb means “to hasten,” “to urge,” “to incite.” The meaning here is that Israel hurried away in great alarm. Compare the same root rendered as “tremble” (ch. 20:3). Compare Ex. 12:11, 34, 39, where it is stated that Israel did not take time to put leaven in their dough (see Isa. 52:12).
Remember the day. See Deut. 4:9; Ex. 13:8.
