R. Yossi Haglili says: An analogy: A man inherits a beth kor (of land) and sells it for a pittance — whereupon the buyer goes and opens springs in it and plants in it gardens and orchards — whereupon the seller begins "choking" (at what he did)! Thus, with Egypt. They sent without realizing what they were sending. Of them it is written in the Tradition (Song of Songs 4:13) "Your 'sendings' are an orchard of pomegranates!"
