הלכה אויף דברים 26:12

Why does one not add "Amen" to the blessing one has said on partaking of fruit etc.? Because it is a single blessing, and Amen is only added to a final blessing, when preceded by one or more blessings; for example, the blessings recited by the King or the High Priest,^*Mentioned in Mishnah Sotah, chapter I, paragraph 1 and set forth in detail in paragraphs 7 and 8. Paragraph 7:—Blessings recited after reading by the High Priest, or someone else, in his presence, during the night of the Day of Atonement, sections from the Book of Leviticus appertaining to the Day (Leviticus ch. 16 and ch. 23:26-32). Paragraph 8:—Blessings after recital in public of passages from the Book of Deuteronomy, on the second evening of the Feast of Tabernacles after the close of the Sabbatical year. This in accordance with the precept (Deuteronomy 31:10-13). The reading was done in the courtyard of the Temple on Mount Zion. The King was the Reader. If there was no King, the chief leader of the people was the reader. The passages read were Deuteronomy 1:1 till 6:9; 11:13 till 11:21; 14:22 till 14:29; 26:12 till 26:15, 17:15 till 17:20; chapter 28; and 17:15 till 17:20 were repeated. the addition of the Amen in these cases indicating that all the blessings had been completed.

According to this system, they should tithe, in a seven year cycle, the first, second, fourth, and fifth years, but on the third and the sixth years of the seven year cycle, after one has tithed ma'asér rishon, one should take out from the remainder another tithe [one-tenth] and give it to the poor. This is called ma'esar ani. In these two years there is no ma'asér sheni but instead ma'esar ani.¹¹⁸See Babylonian Talmud Rosh Hashanah 12b. About this it is written, (Deut. 14:28-29) Every third year you shall bring out the full tithe of your yield of that year, but leave it within your settlements. Then the Levite, [who has no hereditary portion as you have, and the stranger, the fatherless, and the widow in your settlements shall come and eat their fill, so that the LORD your God may bless you in all the enterprises you undertake.] And about this it is written, (Deut. 26:12) When you have set aside in full the tenth part [of your yield in the third year--the year of the tithe--and have given it to the Levite, the stranger, the fatherless, and the widow, that they may eat their fill in your settlements].

When the poor pass by an owner of a field, and he has ma'esar ani, he gives to each poor person who comes before him his fill from the tithe, as it is said, (Deut. 14:29) In your settlements shall come and eat their fill.
