Medieval Latin biblia is short for biblia sacra "holy book", while biblia in Greek and Late Latin is neuter plural (gen. It gradually came to be regarded as a feminine singular noun (biblia, gen. Bruce notes that Chrysostom appears to be the first writer (in his Homilies on Matthew, delivered between 386 and 388) to use the Greek phrase ta biblia ("the books") to describe both the Old and New Testaments together.
bibliae) in medieval Latin, and so the word was loaned as a singular into the vernaculars of Western Europe. By the 2nd century BCE, Jewish groups began calling the books of the Bible the "scriptures" and they referred to them as "holy", or in Hebrew כִּתְבֵי הַקֹּדֶשׁ (Kitvei hakkodesh), and Christians now commonly call the Old and New Testaments of the Christian Bible "The Holy Bible" (in Greek and is now usually cited by book, chapter, and verse.
byblos, "Egyptian papyrus", possibly so called from the name of the Phoenician sea port Byblos (also known as Gebal) from whence Egyptian papyrus was exported to Greece. The division of the Hebrew Bible into verses is based on the sof passuk cantillation mark used by the 10th-century Masoretes to record the verse divisions used in earlier oral traditions.
The oldest extant copy of a complete Bible is an early 4th-century parchment book preserved in the Vatican Library, and it is known as the Codex Vaticanus.
The Christian Old Testament overlaps with the Hebrew Bible and the Greek Septuagint; the Hebrew Bible is known in Judaism as the Tanakh.
The New Testament is a collection of writings by early Christians, believed to be mostly Jewish disciples of Christ, written in first-century Koine Greek.
This ratio is the same for all organisms across the globe at a given time due to the mixing of the atmosphere mentioned above.
(This, in turn, is caused by variations in the magnetic fields of the earth and sun, for example.) Although the ratio of radiocarbon to stable carbon in the atmosphere has varied over time, it is quite uniform around the globe at any given time because the atmosphere mixes very quickly and constantly.
Plants obtain all their carbon atoms from the atmosphere.
From then on, the ratio of radiocarbon to stable carbon will decrease, because the unstable radiocarbon atoms will slowly decay. From this measurement the age in radiocarbon years is calculated. Modern radiocarbon dates are calibrated using long tree-ring chronologies.
After about 50,000 years, the radiocarbon concentration remaining is too small to be measured for the purpose of radiocarbon dating. This is necessary to remove errors in raw radiocarbon dates caused by fluctuations in the amount of radiocarbon in the atmosphere in the past.
