Maintaining that 'mistaken consecration is regarded as proper consecration', Beth Shammai is obviously of the opinion that the low of absolution is never applicable to consecrated objects. Hence, the comparison made above between the similar expressions of 'this' (from which the law of absolution has been derived) is not required. What, then, is the purpose of the employment of this expression in the Biblical text.

This, implies that only the expressions of the Biblical text as interpreted in Ned. 77b may be used and that only the procedure they imply must be followed.
