Danforth puts so much faith in Elizabeth's testimony because Proctor claims that Elizabeth isn't capable of lying. Proctor confidently states, “In her life, sir, she have never lied… my wife cannot lie. I have paid much to learn it, sir” (111). Elizabeth's testimony is significant to the trial because it'll either make or break Proctor’s accusations towards Abigail. By confirming Proctor’s revelation of his acts of adultery, it confirms everything he claims about Abigail. However, Elizabeth lies to protect Proctor’s reputation which causes all his arguments to topple down. By lying, Elizabeth tells Danforth that John Proctor has been lying. When she lies, it means Abigail isn't a whore but rather she is the innocent girl everyone sees her as.
