Leviticus 25:15

במספר שנים אחר היובל תקנה ACCORDING TO THE NUMBER OF YEARS AFTER THE JUBILEE THOU SHALT BUY [OF THY COMPANION] — This (the following) is the literal sense fitting in the clauses of the verse as required by the context: Scripture intends here to warn against wronging prohibited in the preceding verse: When you sell or buy landed property take into account how many years there are until the Jubilee, and according to the years and the crops of the field which it can be expected to yield shall the vendor sell and the purchaser buy, for in the end he (the purchaser) will have to return it to him (to the vendor) in the Jubilee-year. Consequently if there are only a few years until the Jubilee and this man sells it at a high price it follows that the purchaser has been overreached. If, on the other hand, there are still many years until the Jubilee so that he eats from it many crops the seller is overreached if you give him only a low price. It must therefore be purchased according to the period remaining until the Jubilee. That is what Scripture means when it states: “According to the number of the years of the fruits he shall sell unto ,"thee," i. e. according to the number of years of crops that it (the field) will remain in the hand of the purchaser you shall sell it to him. Our Rabbis, however, derived from here the law that one who sells his field has no right to repurchase it before the elapse of at least two years, — that it must remain in the possession of the purchaser two full years reckoning from date to date, and even though there may be three crops in these two years, as, for instance, if he sold it when it had its corn standing. And in this interpretation the word שני does not lose its literal meaning, viz., that of years, (the words שני תבואות are not taken in this interpretation to mean “two crops” as you might at first think) — the phrase means מספר שנים של תבואות the number of years of crops (i. e. שני is the construct of שנים) and not of years when the corn is smitten by blast, and you know that the minimum number implied in the plural שנים is two (this is how the Rabbis derived the law that the vendor must leave the field at least two years in possession of the purchaser) (Arakhin 29b).

according to the number of years after the jubilee thou shalt buy of thy neighbour, and according to the number of years of the fruits he shall sell to thee:

בְּמִסְפַּ֤ר שָׁנִים֙ אַחַ֣ר הַיּוֹבֵ֔ל תִּקְנֶ֖ה מֵאֵ֣ת עֲמִיתֶ֑ךָ בְּמִסְפַּ֥ר שְׁנֵֽי־תְבוּאֹ֖ת יִמְכׇּר־לָֽךְ׃
