From the early Church Fathers to now.
“And the king of the Assyrians brought people from Babylon, and from Cutha, and from Avah, and from Emath, and from Sepharvaim: and placed them in the cities of Samaria instead of the children of Israel: and they possessed Samaria, and dwelt in the cities thereof.”
“The Hebrews, however, call a guard somer, and thus they also hand on in their tradition that the Samaritans first received this name because the king of the Assyrians sent them to be guards of the land of Israel after the captivity, that is, that other Israel besides Judah, which was taken captive into Assyria because of their many sins.”
“These inhabitants, moreover, he transported to Babylon and Medea and, having brought from various regions the people dwelling in that vicinity, he caused them to dwell in Samaria so that his power might be safeguarded for the future, with loyal inhabitants in possession of the place. When these things had taken place, God, wishing to show his power and that he had given over the Jews not because of any lack of power on his part but because of the sins of those whom he had surrendered to their enemies, sent lions on the barbarians, and these preyed on the entire nation. This was reported to the king, and he sent a certain priest to give to them the laws of God. Nevertheless, not even then were they freed entirely from their impiety, but only partly. However, as time went on they turned away from idols and worshiped God. When things had reached this point, the Jews, finally returning, showed a contentious spirit toward them as foreigners and enemies and named them "Samaritans" after the mountain.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
