When it comes to egg matzah does fruit juice act as a leavening agent? TB Mnakhot 53

With daf TB Menakhot 53 we began the fifth chapter of our massekhet. Our attention returns back to the minkha offering. The minkha offering must be matzah and not hametz (leavened bread-gg) as proved by the Gemara. ““And this is the law of the meal offering: The sons of Aaron shall sacrifice it before the Lord in front of the altar…And that which is left of it Aaron and his sons shall eat; it shall be eaten as matzot (Leviticus 6:7–9). These verses demonstrate that there is a general requirement that meal offerings (the minkha-gg) must be brought as matza.” (Sefaria.org translation)  

One may think that the issue of hametz and matzah is black or white, the bread is either matzah or hametz. Today’s daf introduces a middle stage in between matzah and hametz called si-ur (שִּׂיאוּר). Si-ur refers to dough that has begun to become leavened, but has not yet attained the full status of hametz. The Mishnah in Pesakhim (48b) cites a dispute regarding the physical definition of si-ur: R. Meir defines si-ur as dough whose surface has become pale, while R. Yehuda holds that a dough is not si-ur until it becomes to develop cracks.[1] Rabbi Meir classifies si-ur as a subcategory of hametz. This is in contrast to R. Yehuda who views si-ur as neutral-neither hametz nor matzah.

Up to now we’ve described a minkha offering as flour mixed with oil. For the first time we hear that warm water is also part of the recipe. “§ Rabbi Perida raised another dilemma before Rabbi Ami: From where is it derived with regard to all the meal offerings that must be brought as matza that they are kneaded with lukewarm water so that the dough will be baked well, as only a small amount of oil is added, and that one must watch over them to ensure that they do not become leavened while kneading and shaping them? Shall we derive this halakha from the prohibition concerning leavened bread on the festival of Passover, as it is written: “And you shall watch over the matzot (Exodus 12:17), which indicates that one must watch over any dough that is supposed to be made into matza, to ensure that it does not become leavened?” (Sefaria.org translation) The answer is yes. This is the source that warm water is also added to the minkha offering.

Water is the magic ingredient that causes the dough to rise as the above text proves. Once one adds water the dough needs to be watched to make sure it doesn’t become hametz. The Rishonim debate whether fruit juice acts like water as a leavening agent as well.

Ramban holds that if the minkha offering contains fruit juice and oil, it can never become hametz. Olive oil is no less a fruit juice than grape juice. The above text read smoothly. Only when water and not fruit juice is added to the mixture of flour and oil does one have to be careful that does not become leavened.

Rambam disagrees. Even just fruit juice by itself mixed with flour, the dough can become hametz.

Is egg matzah permitted on Passover since fruit juice is part of the recipe? Go ask your Rabbi for the answer of this question.

Modern idolatry #KiTisa#devartorah#parashathashavua

When we hear the word idol, we think of a statue of a person or animal that is the focus of worship. For example in this week’s Torah portion, Ki Tisa, we think of the golden calf the Israelites made soon after they left Egypt (Ex. 32:1-6). We know that God abhors such images (Go back to the 10 Commandments and reread Exodus 20:4-6), yet is it possible that we worship idols without knowing it?

I read about a woman who kept her car in showroom condition. One night her garage caught on fire, and her neighbors had to restrain her from rushing into the flames to rescue her car. As it exploded, she realized that she had nearly sacrificed her life for that car. It had become an idol.

Abraham Joshua Heschel in his book God in Search of Man explains what an idol is. “A thing, a force, a person, a group, an institution or an ideal, regarded as supreme.  God alone is supreme. The prophet abhors idolatry. He refuses to regard the instrumental as final, the temporal as ultimate. “(page 415)

In modern times, when very few Jews are tempted to worship idols in the older sense, we like the woman above worship idols of our own making, like power, prestige, fame, and wealth. Jewish thinkers have called attention to different forms of idolatry‑-the worship of the leader, for instance, as in totalitarian regimes, or the worship of causes, persons, and “isms” of various kinds. 

What’s the supreme and ultimate focus of your life? The answer may surprise you. Shabbat Parah begins our spiritual preparation for Passover and hopefully our final redemption. Now is the time for a course correction.
