The eavesdropper E is usually chosen as Eve who may be listening (i.e., eavesdropping). If the message is not secure, Eve will understand the message.

A traditional "wiretap" was a connection to a physical communication line, such as a telegraph or phone line, that allowed someone (e.g., authorities) to listen to conversations.
In modern times, the "wiretap" idea was extended to wireless communication.

In 2 Kings 6:11 we read of one of the first "wiretaps" of the King of Syria. It is a wireless "wiretap". The king thinks that there is a spy in his headquarters.

The king is told that there is no spy, but that Elisha has a (wireless) "wiretap" on all his communications - even to his bedroom.

The king sends troops to get Elisha. That is, "search and seize". God protects Elisha.

A MITM (Man in the Middle) attack has Eve between Alice and Bob such that the message can not only be understood, but changed.

• Man in the middle
• Meddler in the middle
• Person in the middle
• Machine in the middle
• Monkey in the middle
• Monster in the middle

The historical example a MITM is that of Mary Queen of Scots in the Tower of London.
Her code was broken and a MITM attack used to determine the identity of her co-conspirators.

Since it is hard to break secure communications, hacker attacks on computers will try to establish a MITM attack to steal passwords, credit card numbers, etc. This is usually set up by a phishing attack where the user clicks on a link that creates the MITM situation on the user's computer.

This is a form of "inside" attack since security would not allow an outside attack. However, the user can let the enemy (hacker's code) inside by a click at the computer by the user.

At some point, Eve can impersonate or spoof a message from Alice without Alice doing anything.

This is the primary problem in email phishing attacks where someone pretends to be someone they are not. That is why hackers try to get personal information about people and groups. They can then send messages that appear to be from friends or fellow workers.

Many times, I have heard someone tell someone else that their Facebook account was "hacked" and that they need to change their password.

What happened is that someone created a fake account using their name and then "spoofed" other accounts to make them think it was another person.

The original account of that person was not "hacked". A fake account "spoofed" that person.

The English word "authentic" is, through French, from the Latin word "authenticus" ≈ "authentic, genuine" which is from the ancient Greek word "αὐθεντικός" ≈ "authentic, authoritative".

The root word is the ancient Greek word "αὐθέντης" ≈ "perpetrator" and was often associated with a murderer (or suicide or self-murder) or an absolute ruler. The meaning of the parts is "auto" for "self" and "prepare" or "succeed".

The modern Greek word "αυθεντικός" (av-thehn-tee-KOS) ≈ "genuine".

The ancient Greek word "ἡσυχία" ≈ "peace, silence, stillness, rest". The ancient Greek word "αὐθεντικός" ≈ "authentic, authoritative".

The ancient Greek word "αὐθεντικός" ≈ "authentic, authoritative" word appears only here, to Timothy as Bishop of Ephesus, a Greek city which would know the history and meaning of this word.
Discussion question: Is the question of women teaching something Paul intended as a "vitamin" for this particular city and specific circumstances are is this a "vitamin" that is to be applied everywhere?

The next verses provide Paul's reasoning.

Discuss: Do you consider Paul's reasoning valid? Why or why not?

There are various ways that concepts from security authentication can be used to authenticate the Bible as true (in reality and not as a logical system).
