From: Rabbi Moshe Sofer
To: Rabbi Moshe Tamar
The question is why Chazal understand 'devash' in the Seven Species verse as specifically date honey. The Chasam Sofer proposes that the bikkurim requirement of 'meireishis' (the choicest) narrows the obligation to date honey as the finest form of sweetness.
