Answer:
Rule of law, limited government.
Step-by-step explanation:
These are the two concepts that are explained in this passage. The constitution tells us that the rule of law is to be respected when it states that the government "may be a government of laws and not of men." This means no one is above the law, and institutions have to follow this as well. Moreover, the passage talks about limited government by stating that each power has its duties, and they are not allowed to perform the duties of any other branch of government.
