רמב"ן — ואת ענבי נזירך לא תבצור

Q — In the shemita verse, 'את ספיח קצירך לא תקצור ואת ענבי נזירך לא תבצור' — what is 'ענבי נזירך'? Rashi: from נזר/הפרש — grapes you separated and kept (didn't make hefker); the prohibition is to harvest them as in regular years instead of from the hefker portion.

A — Ramban: 'ענבי נזירך' parallels 'ספיח קצירך' as the same idea in two crops — field and vineyard. 'נזיר' describes the vineyard, not a status the owner imposed on his grapes: an unworked, unpruned vineyard, abandoned by its owner ('הזירו והפרישו ממנו כאילו אינו שלו'), so its grapes grew on their own — exactly as ספיח denotes spontaneous grain growth. Onkelos translates 'שבקך' (he abandoned them), reinforcing this. A wonderful linguistic suggestion: an abandoned vineyard may be called 'נזיר' because a nazir is forbidden grapes and wine and consequently doesn't tend his vineyard. Long hair gets the same etymology: 'גזי נזרך והשליכי.'
