Yerushalmi Nedarim 8:4 ירושלמי נדרים ח׳:ד׳

MISHNAH: ‘Until the fig harvest⁵⁰This is the conclusion of the Halakhah. Biblically, קַיִץ, from קצה “to cut”, is the harvest of any fruit ripening in the summer which is cut from the tree by a knife (and also means “summer”)., until there be fig harvest’, until people start to bring in baskets. ‘Until the fig harvest is over’, until people fold their knives. ‘Until the grain harvest’, until people start to cut wheat but not barley⁵¹Which is harvested in early spring.; everything follows the place of the vow, if made on the hills, on the hills, if made in the plain, in the plain.

HALAKHAH: ‘Until the fig harvest, until there be fig harvest’, etc. “baskets”. Baskets of figs or baskets of raisins⁵³Raisins are transported in baskets in contrast to grapes which are harvested into vats, so as not to lose the juice flowing from injured grape berries. (Cf. Babli 61a).? Let us hear from this: “Until they fold the knives”. You have to say, knives for figs, not knives for raisins⁵⁴Raisins do not need knives.. Let us hear from the following: ⁵⁵This text is from Demay 2:1, Notes 105–107. A load of raisins came up to Tiberias. Gamliel the twin asked Rebbi Abba bar Zavda. He said to him: All of the Land of Israel does not produce a load of raisins. ⁵⁶In the text of Demay, there follows a rhetorical question: Does the entire Land of Israel not produce a load of raisins? But so he said to him: No single place in the land of Israel produces a load of raisins⁵⁷Therefore, the Mishnah must speak of the fig harvest..

“Until the grain harvest”. It is written⁵⁸Ruth 2:23. It is clear from the narrative that there was one continuous harvest activity, the wheat harvest following the barley harvest immediately. Therefore, the Mishnah seems unjustified in denying that “harvest” cannot refer to barley harvest., “until the end of the barley harvest and the wheat harvest”. That verse speaks of the South⁵⁹Bethlehem., the Mishnah of Galilee.

If he made a vow “until the fig harvest” in Galilee and descended into the valleys. Even though the fig harvest did start in the valleys, he is forbidden until it starts in Galilee⁶⁰Tosephta 4:7, Babli (as tannaїtic statement) 63a..
