Which meal offering from the following is brought from barley and not from wheat?
Rambam states that the exceptions to wheat-flour are the jealous wife offering and the omer; the jealous wife offering is indeed from barley.
Question 2
What is the basic measure of oil in meal offerings brought to the altar?
It is explicitly stated in the law: one log of oil for each tenth; unlike incense, where one handful is given to the meal offering even if there are multiple tenths.
Question 3
How are the remnants of a meal offering judged when the identity of the offerer is uncertain between a priest and an Israelite?
They are stringent on both sides: they perform a handful as an Israelite, but do not eat when it is from a priest; therefore, the remnants are not eaten but scattered to the refuse heap.
Question 4
Which action can incur lashes even if the person later just sat and the dough leavened by itself?
The mere act of placing leaven is considered an act of leavening, and thus carries an obligation even though the continuation of leavening happened by itself.
Question 5
Where are the grinding and sifting of the fine flour for meal offerings done according to this chapter?
Rambam distinguishes: grinding and sifting are done outside, but at night/kneading/baking are done in the courtyard under the supervision of the Temple.
