כִּֽי־יִקַּ֥ח אִ֛ישׁ אִשָּׁ֖ה וּבְעָלָ֑הּ וְהָיָ֞ה אִם־לֹ֧א תִמְצָא־חֵ֣ן בְּעֵינָ֗יו כִּי־מָ֤צָא בָהּ֙ עֶרְוַ֣ת דָּבָ֔ר וְכָ֨תַב לָ֜הּ סֵ֤פֶר כְּרִיתֻת֙ וְנָתַ֣ן בְּיָדָ֔הּ וְשִׁלְּחָ֖הּ מִבֵּיתֽוֹ׃
사람이 아내를 취하여 데려온 후에 수치되는 일이 그에게 있음을 발견하고 그를 기뻐하지 아니하거든 이혼 증서를 써서 그 손에 주고 그를 자기 집에서 내어보낼 것이요
Rashi
Where it cannot be demanded - [that is, where] her oath cannot [be imposed] by one witness, as is stated there: that two witnesses who saw that she secluded herself are required, which is derived from [the word] "matter" (Deuteronomy 19:15) [concerning the halakhot of monetary matters and the same word for] "matter" (Deuteronomy 24:1) [concerning the sota]. (Sotah 3b:19)
Bartenura
הזורק. הרי זו מגורשת – As it is written (Deuteronomy 24:1): “…[and he writes her a bill of divorcement], hands it to her...,” and since it is not written, “and in her hand he should give it,” implying nevertheless, “and he gives,” whether in her court or in her garden or in her enclosure. And [it means] that she is standing at the side of her house or at the side of her courtyard.
Bartenura
נקנית בכסף – We learn/derive [through an analogy – Gezarah Shavah – of the words] קיחה קיחה from the field of Ephron. It is written here (Deuteronomy 24:1): “A man takes a wife [and possesses her],” and it is written there (Genesis 23:13): “Let me pay the price of the land; accept it from me, [that I may bury my dead there].”
