Reference for Zevachim 47:15

אלא אמר רבא לעולם אית ליה ג"ש והכי קאמר וכי נאמרה יד בקבלה הואיל ולא נאמר' יד בקבלה אלא אצבע ואי אפשר לקבלה באצבע קיבל בשמאל כשר

Said R'Simeon: is then 'hand' stated in connection with receiving? Rather, [interpret it thus:] 'with his finger he shall put' teaches that the application must be with the right; [and] since 'hand' is not stated in connection with receiving, if he received [it] with his left [hand], it is fit.<span class="x" onmousemove="('comment',' It is now assumed that R. Simeon agrees that 'hand' means the right, but not 'finger'.');">¹⁵</span>
