Exodus 12:19
Brenton's English Septuagint · Berean Standard Bible
Seven days leaven shall not be found in your houses; whosoever shall eat anything leavened, that soul shall be cut off from the congregation of Israel, both among the occupiers of the land and the original inhabitants.
For seven days there must be no leaven found in your houses. If anyone eats something leavened, that person, whether a foreigner or native of the land, must be cut off from the congregation of Israel.
