Reference for Bekhorot 119:27

קרא לתשיעי עשירי ולעשירי עשירי ולאחד עשר עשירי אין אחד עשר מקודש

IF HE CALLED THE NINTH THE TENTH, THE TENTH THE TENTH AND THE ELEVENTH THE TENTH, THE ELEVENTH IS NOT CONSECRATED.<span class="x" onmousemove="('comment',' Since sometimes the eleventh can receive the comparatively stringent holiness of a peace-offering, when, for example, he made a mistake and called the tenth the ninth, then in this case when he called the tenth the tenth, the eleventh receives no holiness at all. The ninth, however, will retain the minor holiness of not being eaten unless blemished, even where he called the tenth the tenth.');">²³</span>
