Ketef Hinnom scrolls
The Ketef Hinnom scrolls, also described as Ketef Hinnom amulets, are the oldest surviving texts currently known from the Hebrew Bible, dated to 600 BC. The text is from the Book of Numbers in the Hebrew Bible, and has been described as "one of most significant discoveries ever made" for biblical studies. The two silver scrolls were uncovered in 1979 at Ketef Hinnom, an archaeological site southwest of the Old City of Jerusalem, which were found to contain a variation of the Priestly Blessing, found in . The scrolls were dated paleographically to the late 7th or early  6th century BCE, placing them in the First Temple period. Discovery. The scrolls were found in 1979 in Chamber 25 of Cave 24 at Ketef Hinnom, during excavations conducted by a team under the supervision of Gabriel Barkay, who was then professor of archaeology at Tel Aviv University. The site appeared to be archaeologically sterile (the tomb had last been used for storing rifles during the Ottoman period), but a chance discovery by a 13-year-old "assistant" revealed that a partial collapse of the ceiling long ago had preserved the contents of Chamber 25. A reconstruction indicates that there  were five chambers and a central 'hall' in cave 24. The cave could hold about 22+ bodies on benches, each with a headrest of stone. Under three of the chambers in the cave there were repositories. The repositories were used for secondary burial, which means that the bones and other remains of the long deceased body were removed and put into the repository, thus making space for another body on that particular bench. The chambers were neatly cut with smoothed surfaces using the royal cubit as measure. The repositories, such as that under chamber 25, had rough surfaces and  a sack-like form, thus it was not intended to be seen. Ketef Hinnom cave 24 has a similar outline and capacity as the Mamilla cave complex 1 and 2, however, these cave complexes have more rooms than cave 24 at Ketef Hinnom. To accommodate more people Ketef Hinnom cave 24 has used the large chamber to the right to accommodate about 10 people, whereas this room in the Mamilla cave complexes did not have benches, thus probably they were used for chemical treatment of the bodies. The repository under chamber 25 contained approximately 60 cm of material with over  a thousand objects: many small pottery vessels, artifacts of iron and bronze (including arrowheads), needles and pins, bone and ivory objects, glass bottles, and jewelry including earrings of gold and silver. In addition, the excavators found two tiny silver scrolls, referred to below as KH1 and KH2. The tomb had evidently been in use for several generations from about 650 BCE, that is towards the end of the First Temple period, and it continued to be used after the destruction of Jerusalem in 587/6 BCE. KH1 was found in Square D, the middle of the repository, 7 cm above the  floor, while KH2 was found while sifting dirt from the lower half of the deposits in Square A, the innermost portion of the repository. Both amulets were separated from Hellenistic artifacts by 3 meters of length and 25 cm of depth, and embedded in pottery and other material from the 7th/6th centuries BCE. Barkay initially dated the inscriptions to the late-7th/early-6th centuries BCE, but later revised this date downward to the early 6th century on paleographic grounds (the forms of the delicately incised paleo-Hebrew lettering) and on the evidence of the pottery found in the immediate vicinity. This  dating was subsequently questioned by Johannes Renz and Wolfgang Rollig, who argued that the script was in too poor a condition to be dated with certainty and that a 3rd/2nd century BCE provenance could not be excluded, especially as the repository, which had been used as a kind of "rubbish bin" for the burial chamber over many centuries, also contained material from the fourth century BCE. A major re-examination of the scrolls was therefore undertaken by the University of Southern California's West Semitic Research Project, using advanced photographic and computer enhancement techniques which enabled the script to be  read more easily and the paleography to be dated more confidently. The results confirmed a date immediately prior to the destruction of Jerusalem by the Babylonians in 586/7 BCE. Kyle McCarter of Johns Hopkins University, a specialist in ancient Semitic scripts, has said the study should "settle any controversy over [the date of] these inscriptions". Significance. The 2004 team described the scrolls as "one of most significant discoveries ever made" for biblical studies. Apart from their significance for our knowledge of the development of the Hebrew alphabet, the scrolls "preserve the earliest known citations of texts also found in the  Hebrew Bible and ... the earliest examples of confessional statements concerning Yahweh." The reference to Yahweh as "Rebuker of Evil," found in later incantations and amulets associated with Israel, is evidence that these artifacts were also amulets. Dr. Wayne Pitard has stated that although evidence for the antiquity of the Priestly Blessing is now compelling, this does not necessarily mean that the Book of Numbers already existed at that time. Dr. James R. Davila has similarly pointed out that while the scrolls show that "some of the material found in the Five Books of Moses existed in the First Temple period , the suggestion that they are proof that the Five Books of Moses were in existence during the First Temple period" (as described in an article in the Israeli newspaper "Haaretz") is "an overinterpretation of the evidence." According to the team which led the most conclusive reexamination of the scrolls: Description. The scrolls are known as KH1 and KH2. They are written in Paleo-Hebrew characters (see Paleo-Hebrew alphabet) not the Aramaic square script more familiar to most modern readers. Text below in square brackets represents informed deduction. KH1. The scroll KH1 measures . Biblical parallels. Compare lines 3–6 to: The  omission of "thousands" may have originally appeared on line 7 as in Deuteronomy 7:9. KH2. The scroll KH2 measures . Biblical parallels. Compare lines 5–12 to Numbers : <poem>6:24 Yahweh bless you and keep you; 6:25 Yahweh make his face shine upon you, and be gracious to you; 6:26 Yahweh lift up his countenance upon you, and give you peace.</poem> (Note that the two bold italicized phrases above are not present on this scroll; also note that all of Numbers 6:25–26 may have appeared on KH1 after line 18 where the scroll has disintegrated). Apotropaic nature of the amulets. Jeremy  Smoak has argued that the combination of the terms "guard" and "protect" is typical of apotropaic amulets and find parallels among Phoenician and Punic amulets from the Iron Age. He finds reflection of the custom of making such apotropaic amulets in Psalm 12:7–9:
