עַשֵּׂ֣ר תְּעַשֵּׂ֔ר אֵ֖ת כָּל־תְּבוּאַ֣ת זַרְעֶ֑ךָ הַיֹּצֵ֥א הַשָּׂדֶ֖ה שָׁנָ֥ה שָׁנָֽה׃
Thou shalt surely tithe all the increase of thy seed, that which is brought forth in the field year by year.
Targum Jonathan on Deuteronomy
Be mindful to tythe your fruitage of whatsoever cometh forth, and which you gather in from the field year by year; not giving the fruit of one year for the fruit of another.
Targum Jerusalem
My people of the house of Israel, tything you shall tythe all the produce of your seed, of that which you sow upon the face of the field and gather in the produce of each year. Israel, My people, it is not lawful for you to tythe and eat the fruit of one year along with the fruit of (another) year.
