Book of Genesis The Book of Genesis (from the Latin Vulgate, in turn borrowed or transliterated from Greek γένεσις, meaning "Coming into Being"; Hebrew: בְּרֵאשִׁית‎, Bərēšīṯ, "In [the] beginning") is the first book of the Hebrew Bible (the Tanakh) and the Christian Old Testament.[1]
Book of Joshua The Book of Joshua (Hebrew: ספר יהושע‎ Sefer Yĕhôshúa) is the sixth book in the Hebrew Bible (the Christian Old Testament) and the first book of the Deuteronomistic history, the story of Israel from the conquest of Canaan to the Babylonian exile.[1]:42 It tells of the campaigns of the Israelites in central, southern and northern Canaan, the destruction of their enemies, and the division of the land among the Twelve Tribes, framed by two set-piece speeches, the first by God commanding the conquest of the land, and, at the end, the last by Joshua warning of the need for faithful observance of the Law (torah) revealed to Moses.[2]
