Parallel
Exodus 12:15
Brenton's English Septuagint · Berean Standard Bible
Seven days ye shall eat unleavened bread, and from the first day ye shall utterly remove leaven from your houses: whoever shall eat leaven, that soul shall be utterly destroyed from Israel, from the first day until the seventh day.
For seven days you must eat unleavened bread. On the first day you are to remove the leaven from your houses. Whoever eats anything leavened from the first day through the seventh must be cut off from Israel.
