Adam Clarke on Proverbs 24:11

If thou forbear to deliver - If thou seest the innocent taken by the hand of lawless power or superstitious zeal, and they are about to be put to death, thou shouldst rise up in their behalf, boldly plead for them, testify to their innocence when thou knowest it; and thus thou wilt not be guilty of blood; which thou wouldst be, if, through any pretense, thou shouldst neglect to save the life of a man unjustly condemned.
