“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?
“In encounters with the forces of Timothy and Bacchides, they killed more than twenty thousand of them. They got possession of some exceedingly high strongholds. They divided a very great amount of plunder. They give it to those who had been tortured, to the orphans, widows, and aged, shares equal to their own. They collected the arms of the enemy. They carefully stored them all of them in strategic places. They carried the rest of the spoils to Jerusalem. They killed the commander of Timothy’s forces, a most unholy man, one who had greatly troubled the Jews. While they were celebrating the victory in the city of their ancestors, they burned those who had set fire to the sacred gates, Callisthenes and some others. They had fled into one little house. Thus they received the proper recompense for their impiety.”
This is loosely connected to stories and battles in 1 Maccabees, chapters 5 and 7. Timothy was a leader of the gentiles on the east side of the Jordan River. Bacchides was a governor and general of King Demetrius I. Both of them were considered the enemy. These enemy troops had lost 20,000 men. The spoils had been taken and distributed to the tortured, the widows, the orphans, and the aged. However, they always kept some for themselves as they had done with the spoils from the defeat of Nicanor. Here it says that they had killed the commander of the troops of the unholy man Timothy. When they were celebrating in Jerusalem, they also burned the house of this unknown man named Callisthenes and others because they had been impious. Perhaps these were the Hellenizing Jews in Jerusalem.
