Matthew Poole and continuators on Exodus 12:19

19 Seven dayes shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the Congregation of Israel, whether he be a stranger , or born in the land .

To wit, a Profelite: for strangers unconverted to the Jewish Religion were not obliged nor admitted to the celebration of the Passe-over or Feast of unleavened Bread. Though I see no inconvenience, if all Strangers though Heathens, were forbidden to have or use any unleavened Bread at that time, lest the Jews who conversed with them might be tempted to desire or partake of it with them.

To wit of Canaan which I have promised to you and to which I am now leading you, which was so well known to all of them that it was needless to express it in this place.
