19 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.
*Minor differences ignored. Grouped by changes, with first version listed as example.
Born in the land - A stranger or foreigner might be born in the land, but the word here used means "a native of the land," belonging to the country by virtue of descent, that descent being reckoned from Abraham, to whom Canaan was promised as a perpetual inheritance.
No leaven found in your houses - To meet the letter of this precept in the fullest manner possible, the Jews, on the eve of this festival, institute the most rigorous search through every part of their houses, not only removing all leavened bread, but sweeping every part clean, that no crumb of bread shall be left that had any leaven in it. And so strict were they in the observance of the letter of this law, that if even a mouse was seen to run across the floor with a crumb of bread in its mouth, they considered the whole house as polluted, and began their purification afresh. We have already seen that leaven was an emblem of sin, because it proceeded from corruption; and the putting away of this implied the turning to God with simplicity and uprightness of heart. See on Exodus 12:8 (note), and Exodus 12:27 (note).
Seven days there shall be no leaven found in your houses,..... Wherefore, on the fourteenth day the most diligent search was made, and whatever was found was burnt, or cast into the sea, or dispersed with the wind; about which the traditionary writers of the Jews, give many rules and canons; see Gill on Exodus 12:15,
for whoso eateth that which is leavened, even that soul shall be cut off from the congregation of Israel; which is repeated to deter them from the breach of this ordinance; See Gill on Exodus 12:15, and it is added for further explanation, of whom it concerns:
whether he be a stranger, or born in the land; by a "stranger" is meant, not a mere Heathen, who was not bound by this law, but a proselyte; and not a proselyte of the gate, one that was only a sojourner among them, and observed the commandments of the sons of Noah; but a proselyte of righteousness, who professed the Jewish religion, and proposed to conform to it in all respects, and therefore was obliged to observe this as other precepts: and by one "born in the land", is intended a native of the land of Canaan, whither they were now going in order to possess it, or a real Israelite, such as were born of Israelitish parents, and proper inhabitants of Canaan, which they would be put into the possession of.
stranger--No foreigner could partake of the passover, unless circumcised; the "stranger" specified as admissible to the privilege must, therefore, be considered a Gentile proselyte.
A stranger - A proselyte. Heathens were not concerned in the passover.
