Leviticus 25:5

25:5 You must not gather in the aftergrowth of your harvest and you must not pick the grapes of your unpruned ¹  vines; the land must have a year of complete rest.

[25:5]  ¹ tn Heb “consecrated, devoted, forbidden” (נָזִיר, nazir). The same term is used for the “consecration” of the “Nazirite” (and his hair, Num 6:2, 18, etc.), a designation which, in turn, derives from the very same root.
