The Gemara employed to deduce that the term , "yamim", (literally "days") sometimes means "a year," and Rab Hisda thus interpreted the word , "yamim", in to mean "a year." says, "And her brother and her mother said: ‘Let the maiden abide with us , "yamim", at the least ten." The Gemara reasoned that if , "yamim", in means "days" and thus to imply "two days" (as the plural implies more than one), then would report Rebekah's brother and mother suggesting that she stay first two days, and then when Eliezer said that that was too long, nonsensically suggesting ten days. The Gemara thus deduced that , "yamim", must mean "a year" in , as implies when it says, "if a man sells a house in a walled city, then he may redeem it within a whole year after it is sold; for a full year (, "yamim") shall he have the right of redemption." Thus might mean, "Let the maiden abide with us a year, or at the least ten months." The Gemara then suggested that , "yamim", might mean "a month," as suggests when it uses the phrase "a month of days (, "yamim")." The Gemara concluded, however, that , "yamim", means "a month" only when the term "month" is specifically mentioned, but otherwise means either "days" (at least two) or "a year."
