Why go after a corrupted copy if you have the original?
For sects and slanderers let there be no hope, and may all the wickedness in an instant perish, and may all Your enemies speedily be cut down... (Twelfth blessing of Amida prayer)
Who are the Samaritans?
According to the book of II Kings (17:24) Samaritans are a group of pagan people that were moved into the land of Israel by a babylonian emperor, while exiling the Jews into Babylonia. This group (known as Kuthim) eventually was attacked by wild animals, and started to fear the "G-d of the (local) land". When the news reached the emperor, he sent a Jewish high priest to teach them "the law of the G-d of the land." The high priest taught them, but not enough. Kuthim eventually became a monotheistic people (intermixed with some Jews), but did not exactly follow Judaism. (II Kings, 17:24)
The following archaeological discoveries, support the Book of Kings.
(Sargon II Inscriptions, COS 2.118A, p. 293) "[the Samar]ians [who had agreed with a hostile king]...I fought with them and decisively defeated them]....carried off as spoil. 50 chariots for my royal force ...[the rest of them I settled in the midst of Assyria]....The Tamudi, Ibadidi, Marsimani and Hayappa, who live in distant Arabia, in the desert, who knew neither overseer nor commander, who never brought tribute to any king--with the help of Ashshur my lord, I defeated them. I deported the rest of them. I settled them in Samaria/Samerina."
(Nimrud Prisms, COS 2.118D, pp. 295-296)" The inhabitants of Samaria/Sa]merina, who agreed [and plotted] with a king [hostile to] me, not to do service and not to bring tribute [to Ashshur] and who did battle, I fought against them with the power of the great gods, my lords. I counted as spoil 27,280 people, together with their chariots, and gods, in which they trusted. I formed a unit with 200 of [their] chariots for my royal force. I settled the rest of them in the midst of Assyria. I repopulated Samaria/Samerina more than before. I brought into it people from countries conquered by my hands. I appointed my eunuch as governor over them. And I counted them as Assyrians."
Was Torah given in Ivri or the Ashuri script? The Jewish view.
TheRitva's commentary on the Talmud (Mesechet Megillah 2b) paraphrases the Jewish view on the two scripts. Torah was given in the Ashuri script. The prove comes from Talmud (Mesechet Megillah 2b), which states that a miracle was needed to hold the letters ם (mem) and ס (samech) on the stone tablets. However, because of script's sanctity, it was not used for mundane writings, but kept in the Holly of Hollies. A non-holy (and easier to write) Ivri script was adopted to the point where even the Torahs used for mass study were written in it. Eventually, the Ashuri script became forgotten by the common people, and was only preserved by the Sages. For this reason, only Daniel (a sage) could decipher the "writings on the wall" (Daniel 5:5 - 5:28), which appeared in the Ashuri script. After the Assyrian-Babylonian exile, the Ashuri script was reintroduced, and gained popularity even among the common people. According to the the Talmud (Mesechet, Sanhendrin 22a) the name Ashuri comes from the fact that its an "upright" (מאושר) script, or because it became popular, when Jews returned from the Assyrian (אשור) exile.
The Dead Sea Scrolls support Ritva's view, in that Ashuri is the holiest script. Most Qumran fragments were written in this script. In many cases, however, G-d's name (YHWH) appears to be referenced to by four dots, or is written in the Ivri script (see picture). The reason? As soon as G-d's name is written in the Ashuri (holly) script, it requires extra care and more caution . For the same reason, Rashi created a new script for his writings that came be known as the Rashi script. . .
Mount Gerizim in the ten commandments?
Samaritans claim that G-d commanded mount Gerizim to be the place of worship, rather than Jerusalem. In fact, their Torah scrolls contain a commandment to build an altar on mount Gerizim (Deuteronomy 5:6 - 5:18). They claim Jews altered the text in order to legitimize the temple in Jerusalem. But the following facts prove the opposite. It is they who altered the text to suit their claim:
Deuteronomy 5:1-25 (known as 4Q41(981)) of the Dead Sea Scrolls does not contain any reference to Mount Gerizim, but matches the Mesoretic Text.
If Mesoretic text was altered, it would have been inclined towards the view of the Jews. However, it isneutralin regards to "place of worship", while the Samaritan text isbiasedtowards Mt. Gerizim.
