The relationship between the Israelites and the priests is built upon a spiritual and economic partnership, expressed through the separation and giving of holy gifts. A clear legal framework governs how sacred property is transferred from the owners to God's servants. At first glance, these contributions appear to be the standard agricultural offerings and tithes separated from the harvest [רשב״ם]. However, the language used to describe the presentation of these gifts suggests an act of bringing them near, a concept usually reserved for sacrifices offered on the altar. Since standard agricultural offerings are not brought to the altar but are instead collected by priests at the local threshing floors [רש״י, רמב״ן, תורה תמימה], the primary approach among commentators is that this refers to the First Fruits. While the Torah requires bringing the First Fruits to God's house, it clarifies here that the physical fruits are given directly to the priest [רש״י, ספורנו]. Some commentators blend these ideas, suggesting that the primary subject remains the standard agricultural offering, but the specific sacrificial language is used to incorporate the First Fruits as well [משכיל לדוד].
The obligation of these gifts is expansive, applying to all types of fruit, not just the staple crops of grain, wine, and oil [תורה תמימה, מלבי״ם]. Furthermore, there is no fixed limit on the amount one can give. If a person wishes, they may dedicate their entire threshing floor as a holy offering or as First Fruits, provided they leave a small amount of regular produce for their own use [רמב״ן, הכתב והקבלה]. The act of physically bringing these gifts to the priest [ביאור שטיינזלץ] carries deep spiritual significance, as handing the gift to God's servant is viewed as an act of drawing closer to God Himself [רש״ר הירש]. Crucially, this transfer must be completely voluntary. The owners must bring and present the gifts of their own free will, and it is strictly forbidden for a priest to take the offerings by force [רמב״ן, הכתב והקבלה].
When it comes to selecting which priest receives the gift, a distinction is made based on the nature of the offering. For holy gifts that do not involve service at the altar, the owner has the right to give them to any priest of their choosing [בכור שור, טור הארוך, רלב״ג]. Conversely, gifts that require a formal presentation at the altar, such as the First Fruits, must be given exclusively to the priests who are actively on duty at the sanctuary at that time [ספורנו, רמב״ן, העמק דבר]. Once the gift is handed over, absolute legal ownership is established. The offering becomes the complete property of the priest, to the extent that he may even use its monetary value to betroth a wife [ברטנורא]. The priest, on his part, cannot refuse to accept the gift that is due to him [אור החיים]. Because the offering is his rightful property, anyone who takes it from him commits theft and is subject to the strict penalties of robbery [טור הארוך, מלבי״ם].
