Rashi on Deuteronomy 28:5/רש"י על דברים כ״ח:ה׳

1ברוך טנאך BLESSED SHALL BE THY BASKET — i.e. thy fruits (which are kept in baskets). — Another explanation of טנאך is that it means liquids which you filter through baskets (wicker work).

2ומשארתך accordingly means dry produce that remains (נשאר) in the vessel and does not flow out.
