"a land flowing with milk and honey": It is written here "a land flowing with milk and honey," and elsewhere (Shemoth 13:1) "a land flowing with milk and honey." Just as there, the land of the five nations (is being referred to), so, here. From here R. Yossi Haglili ruled: Bikkurim are not brought from across the Jordan, it not flowing with milk and honey.
(Devarim, Ibid. 10) "And now": Immediately upon harvesting.
"the first of the fruit of the land": From here they ruled: One goes down to his field, and seeing a fig or a cluster or a pomegranate of the fruit ripening, he ties them with a reed rope over them and says "These are bikkurim."
