We do not give to a poor man who is traveling from place to place, less than a loaf of bread worth a פונדיון, etc. - אין פוחתין לעני העובר ממקום למקום מככר בפונדיון כולי
תמחוי is not distributed at night. An עני is given two meals; one for the upcoming evening meal and one for פת בסלו. There is no concern he will not reach a Jewish settlement before the next meal.
He stayed for שבת; we give him food for three meals - שבת נותנין לו מזון שלש סעודות
The three שבת meals are given for the third שבת meal, the מוצאי שבת meal and one as a meal to go. One may not take from the תמחוי if he has two meals, besides the current meal. If one has sufficient food he should not take from צדקה; if however he does not have enough for even two meals for שבת, he may take three meals for שבת.
