Lumapit sila sa kanya at nagsabi, “Magtatayo kami rito ng mga kulungan ng tupa para sa aming mga hayop, at ng mga lungsod para sa aming maliliit na anak.
Mishnah Bava Batra
The legal period of possession [in order to establish ownership] for houses, cisterns, trenches, caves, dovecotes, bath-houses, olive-presses, irrigated fields and slaves and anything which continually produces a yield is three complete years. The legal period of possession [in order to establish ownership] for a field irrigated by rain water is three years and they need not be completed. Rabbi Yishmael says: “Three months during the first year, and three months during the last year and twelve months during the middle year, which makes eighteen months.” Rabbi Akiva says: “One month during the first year and one month during the last year and twelve months during the middle year, which makes fourteen months.” Rabbi Yishmael said: “When does this apply? With regards to a sown field, but with tree plantation, if he brought in his produce (grapes), collected the olives and gathered in his fig harvest, this counts as three years.”
