a deposition signed by 91 citizens

Explanation:

This deposition was a document signed by 91 citizens that knew Rebeca Nurse and Elizabeth Proctor and that states and defend them saying that they are not involved in witchcraft or are witches, this is to prove their innocence and to be used against the girls who were lying. Howevere the document does not help at all since at the end they all are charged with witchcraft.

faithful servants eumaeus and philaetius:

his ragged vest then drawn aside disclosed the sign conspicuous, and the scar exposed: eager they view'd, with joy they stood amazed with tearful eyes o'er all their master gazed:

these servants know ulysses by the scar he got when he was a child - so when he showed them the mark, they immediately knew this is truly their master and they hugged him, finally starting to believe his words.
