Deuteronómio 26:3 Midrash: Ein Yaakov (Glick Edition), Mekhilta DeRabbi Yishmael & Sifrei Devarim

Whence do we know that the service on the altar, of a priestly son born of a divorced woman or a Chalutza is lawful? Said R. Juda in the name of Samuel: "The passage says (Num. 25, 13) And it shall be unto him and unto his seed after him; i.e., whether it be legal or illegal seeds." The father of Samuel said: "From the following (Deut. 33, 11) Bless, O Lord, his substance, and receive favorably the work of his hands; i.e., even the work of the Chulin should be received favorably." R. Jannai said: "We may infer from the following (Ib. 26, 3) And thou shalt come unto the priest that may be in those days. Is it possible to think that a man will go to a priest who does not live in his days? We must therefore say that the passage refers to a priest who was fit, but afterwards became ineligible [through an unlawful marriage]." Whence do we know that the service of a priest with a blemish is considered defective? Said R. Juda in the name of Samuel: "The passage reads (Num. 25, 12) Wherefore say: Behold, I give unto him My covenant of peace; i.e., the word Shalom means when he is perfect without a blemish, but not when something is missing in his body. How can you take it to mean perfect, since it is written Shalom, which means peace? Said R. Nachman: "The letter Vav of Shalom is shortened and looks like Yud, [hence it may read Shalem, perfect]."

"the first-fruits of your land": to exclude (from the mitzvah of bikkurim) tenant-farmers, renters, thieves and extortionists. (Devarim 26:3) "which the L–rd swore to our fathers": to exclude proselytes and servants. (Ibid.) "which the L–rd your G–d gives to you (singular)": to exclude women, tumtum (indeterminate gender), and hermaphrodite.

"that you bring from your land": so long as they are found on the face of the land. I might think he may bring them before Shavuoth, it is, therefore, written (Shemoth 23:16) "And the feast of the harvest (Shavuoth) of the first-fruits of your work." From when do you bring? From Shavuoth until Channukah. I might think that you recite (the bikkurim formula) whenever you bring them; it is, therefore, written (Devarim 26:11) "and you shall rejoice": There is recitation only at the time of rejoicing, which implies: From Shavuoth until Succoth, one brings and recites; from Succoth until Channukah, one brings but does not recite. R. Yehudah b. Betheira says: He brings and recites.
