וְאִם־לֹ֤א יִגְאַל֙ אֶת־הַשָּׂדֶ֔ה וְאִם־מָכַ֥ר אֶת־הַשָּׂדֶ֖ה לְאִ֣ישׁ אַחֵ֑ר לֹ֥א יִגָּאֵ֖ל עֽוֹד׃
Mais s’il ne rachète point cette terre, ou qu’on l’ait vendue à quelque autre, elle ne pourra plus être rachetée;
Rashi on Leviticus
ואם לא יגאל את השדה AND IF HE WILL NOT REDEEM THE FIELD— “he” means, the man who dedicated it,
Rashbam on Leviticus
ואם מכר..לאיש אחר, “if the Temple treasurer had sold the field to someone else in the meantime;” its original owner can no longer redeem it but it is shared out (the proceeds received by the treasurer) among the priests at the next Jubilee year. It goes to the priests who are performing the duties assigned to them on that date.
Siftei Chakhamim
The Temple treasurer. Explanation: He is the seller and not the ‘one who dedicated’ mentioned above.
