where is the book of jasher mentioned in the bible
Book of Jasher (biblical references) The Book of Jasher is also mentioned in the Biblical Book of Joshua amid the descriptions of Joshua's military exploits in the land of Canaan, specifically after Adonizedek, king of Jerusalem, and his allies attacked Gibeon for allying themselves with Israel and Joshua and the Israelites came to Gibeon's aid (Joshua 9-10). When "YHWH gave the Amorites over to the sons of Israel", Joshua told the sun to stand still over Gibeon and the moon to stand still over Valley of Aijalon (Joshua 9:1-2). Then the Book of Joshua 10:13 states:
Book of Deuteronomy The book consists of three sermons or speeches delivered to the Israelites by Moses on the plains of Moab, shortly before they enter the Promised Land. The first sermon recounts the forty years of wilderness wanderings which had led to that moment, and ends with an exhortation to observe the law (or teachings), later referred to as the Law of Moses; the second reminds the Israelites of the need for monotheism and observance of the laws (or teachings) he has given them, on which their possession of the land depends; and the third offers the comfort that even should Israel prove unfaithful and so lose the land, with repentance all can be restored.[2]
