Reference for Pesachim 97:16

רב אידי בר אבין נסיב כהנתא נפקו מיניה תרי בני סמיכי רב ששת בריה דרב אידי ור' יהושע בריה דרב אידי אמר ר"פ אי לא נסיבנא כהנתא לא איעתרי

But now that R'Hisda said: The controversy is in respect of the second feast,<span class="x" onmousemove="('comment',' After the betrothal the bridegroom (arus) sent gifts to his bride, in connection with which there was a second feast at the father-in-law's house.');">²³</span> but in respect to the first feast all agree that it is a religious [function], you may even say [that] both are [according to] R'Judah, yet there is no difficulty; one refers to the first feast, while the other refers to the second feast.
