יָמִים֙ עַל־שָׁנָ֔ה תִּרְגַּ֖זְנָה בֹּֽטְח֑וֹת כִּ֚י כָּלָ֣ה בָצִ֔יר אֹ֖סֶף בְּלִ֥י יָבֽוֹא׃
After a year and days shall ye be troubled, ye confident women; For the vintage shall fail, the ingathering shall not come.
Rashi on Isaiah
Year after year (lit., ‘days upon a year.’) Comp. (supra 29:1) “Add year to year,” and your sins are constantly becoming more serious, until eventually you shall be troubled, those who are now confident, for the vintage of the grapes shall be over for them, and the ingathering of the grain shall not come into the house.
Rashi on Isaiah
the ingathering (אֹסֶף) This is a noun; therefore, its accent is on the first syllable and it is vowelized with a ‘pattah’ (now called a ‘segol’).
