Talmud for Berakhot 6:6
הָיוּ יוֹשְׁבִין לֶאֱכֹל, כָּל אֶחָד וְאֶחָד מְבָרֵךְ לְעַצְמוֹ. הֵסֵבּוּ, אֶחָד מְבָרֵךְ לְכֻלָּן. בָּא לָהֶם יַיִן בְּתוֹךְ הַמָּזוֹן, כָּל אֶחָד וְאֶחָד מְבָרֵךְ לְעַצְמוֹ. לְאַחַר הַמָּזוֹן, אֶחָד מְבָרֵךְ לְכֻלָּם. וְהוּא אוֹמֵר עַל הַמֻּגְמָר, אַף עַל פִּי שֶׁאֵין מְבִיאִין אֶת הַמֻּגְמָר אֶלָּא לְאַחַר הַסְּעֻדָּה:
If they sat down to eat [without reclining, a sign that they had not arranged to eat together, for when groups of people had arranged to eat together, they would recline on mats, and eat and drink reclining on their left side], each one blesses for himself, [there being no "appointed" meal without reclining. However, if they said: "Let us go and eat bread in that place," even if they did not recline, it is as if they had, and one blesses for all; and they also join together for grace.] If they reclined, one blesses for all. If wine were brought before them during the meal, each one blesses (over the wine) for himself [since their throat is not free, and the recliners are intent not upon the blessing, but upon swallowing what is in their mouths. Or it may be that we are apprehensive of their choking in answering Amen.] And he makes the blessing over the mugmar [The one who makes grace blesses over the mugmar: "Who creates woods of spices." And even though there may be present a person more eminent than he, since he began with one (blessing), he makes the other], even though the mugmar is not brought until after the meal [after grace, so that it is not a requirement of the meal. Still, since he began the latter blessings, he completes them. ["Mugmar": After the meal they were wont to bring wood-spices on a coal-pan, to produce an aromatic fragrance.]
Jerusalem Talmud Sheviit
The argument goes as follows: It is stated in Mishnah 8:1 that animal feed may be used to make wound dressing; only Sabbatical human food may not be used. In itself, animal feed has the sanctity of the Sabbatical and cannot be used for industrial purposes. Then one cannot understand why dyestuff seeds retain their sanctity but wound dressing does not. The answer is that the next argument will show that human needs have precedence over animal needs but once the product is no longer available for all of mankind it cannot have sanctity attached.: “Sanctity of the Sabbatical falls on din, sad, and indigo seed that one sows after the end of the Sabbatical.” What is that? “For you”, for all of you equally. Rebbi Yose in the name of Rebbi Hila understood it from the following (Lev. 25:7)9Sifra Behar Pereq 1(10). “For your domestic animal and the beast in your Land shall be all its yield as feed.” It is clear from the preceding verse that not all growth of the Sabbatical is for animals since humans were given prior permission to eat it. Therefore, the expression “shall be” is interpreted as: All that is not used for humans shall be animal feed.: “Shall be”, even to kindle the light and to dye. Does this not destroy animal feed? Rebbi Mana said, explain it if animal feed is used for human needs and you cannot infer anything from it10For potential human food..
