“If anyone is there,
Who shares in peace,
On that person.
But if not,
It will return
καὶ ἐὰν ἐκεῖ ᾖ υἱὸς εἰρήνης, ἐπαναπαήσεται ἐπ’ αὐτὸν ἡ εἰρήνη ὑμῶν· εἰ δὲ μήγε, ἐφ’ ὑμᾶς ἀνακάμψει.
Luke indicated that Jesus said that if there was a son of peace (καὶ ἐὰν ἐκεῖ ᾖ υἱὸς εἰρήνης) or anyone there who shared in peace, their peace would rest or remain on that person (ἐπαναπαήσεται ἐπ’ αὐτὸν ἡ εἰρήνη ὑμῶν). But if not (εἰ δὲ μήγε), that peace would return to them (ἐφ’ ὑμᾶς ἀνακάμψει). Matthew, chapter 10:13, had something similar when Jesus was talking to his 12 apostles before their missionary expedition. If there were worthy people or the house was worthy, they should let their peace come upon them. However, if they are not worthy or deserving, their peace should return or turn back to them, the same as Luke here. I am not sure how you would get your peace greeting revoked in some way. Have you ever been mad because someone did not return you peace greeting?
“As you enter
If the house
Let your peace
Come upon it.
But if it is not worthy,
Let your peace
Return to you!”
εἰσερχόμενοι δὲ εἰς τὴν οἰκίαν ἀσπάσασθε αὐτήν
καὶ ἐὰν μὲν ᾖ ἡ οἰκία ἀξία, ἐλθάτω ἡ εἰρήνη ὑμῶν ἐπ’ αὐτήν· ἐὰν δὲ μὴ ᾖ ἀξία, ἡ εἰρήνη ὑμῶν πρὸς ὑμᾶς ἐπιστραφήτω.
There are no exact equivalent passages in the other gospels about how to enter into a house. Jesus, via Matthew, had some simple instructions again. As you went into a house (εἰσερχόμενοι δὲ εἰς τὴν οἰκίαν), greet or pay respects to the people in the house (ἀσπάσασθε αὐτήν). If they were worthy people or the house was worthy (καὶ ἐὰν μὲν ᾖ ἡ οἰκία ἀξία), let your peace come upon them (ἐλθάτω ἡ εἰρήνη ὑμῶν ἐπ’ αὐτήν). But if they are not worthy or deserving (μὴ ᾖ ἀξία,), let your peace return or turn back to you (ἡ εἰρήνη ὑμῶν πρὸς ὑμᾶς ἐπιστραφήτω). I am not sure how you would get your peace greeting revoked in some way.
“Then King Artaxerxes said to Queen Esther and to Mordecai the Jew.
I have given Esther the house of Haman.
They have hanged him on the gallows.
Because he plotted to lay hands on the Jews.
You may write as you please with regard to the Jews,
In the name of the king,.
Seal it with the king’s ring.
An edict written in the name of the king
And sealed with the king’s ring cannot be revoked.’”
The king said that he given the house of Haman to Queen Esther. In fact, they had hanged him on his own gallows. She and Mordecai could write what they wanted about the Jews. He was going to give them his signet ring. However, he said that anything that he has written could not be revoked. Therefore, he stood by his original decree that Haman wrote. However, he would stand by anything that they would write also. There could be not revocations. It is interesting to note he took no blame. He seems to say, “Whatever” to every question that comes up.
