Seven days were fulfilled, after Yahweh had struck the river.

"'Seven days you shall eat unleavened bread; even the first day you shall put away yeast out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

Seven days shall there be no yeast found in your houses, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a foreigner, or one who is born in the land.

Seven days you shall eat unleavened bread, and in the seventh day shall be a feast to Yahweh.

Unleavened bread shall be eaten throughout the seven days; and no leavened bread shall be seen with you, neither shall there be yeast seen with you, in all your borders.

You shall do likewise with your cattle and with your sheep. Seven days it shall be with its mother, then on the eighth day you shall give it to me.

You shall observe the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib (for in it you came out from Egypt), and no one shall appear before me empty.

Seven days shall the son who is priest in his place put them on, when he comes into the Tent of Meeting to minister in the holy place.

"You shall do so to Aaron, and to his sons, according to all that I have commanded you. You shall consecrate them seven days.

Seven days you shall make atonement for the altar, and sanctify it: and the altar shall be most holy; whatever touches the altar shall be holy.

"You shall keep the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib; for in the month Abib you came out from Egypt.
