Question

1) Macbeth regrets having killed Duncan but doesn't repent of his sin. As a matter of fact, the word Amen stuck in his throat.
2)Do you say "clean his hands of the burden of the guilt which weighs on his soul?" Is clen followed by "of"?

Answer 1

clen = clean. Yes, clean of (or perhaps from)
