Mischna zu Schemot 23:19

These are the things that have no definite quantity: The corners [of the field]. First-fruits; [The offerings brought] on appearing [at the Temple on the three pilgrimage festivals]. The performance of righteous deeds; And the study of the torah. The following are the things for which a man enjoys the fruits in this world while the principal remains for him in the world to come: Honoring one’s father and mother; The performance of righteous deeds; And the making of peace between a person and his friend; And the study of the torah is equal to them all.

For what reason may he not bring them? Because it is said, “The first-fruits of your land” (Exodus 23:19) until all of their growth is on your land. Sharecroppers, leasers, or occupiers of confiscated property (sikarikon), or a robber does not bring them for the same reason, because it says, “The first-fruits of your land.”

From where do we know that one is responsible [for his bikkurim] until he brings them to the temple Mount? Because it says: “The first of the first-fruits of your land you shall bring into the house of the Lord your God” (Exodus 23:19) this teaches that he is responsible until he brings them to the Temple Mount. If he brought [bikkurim] of one kind and made the recital and then brought of another kind, he does not make a [second] recital.
