In the Hebrew Bible the term used to refer tothe future Transjordan is , "beyond the Jordan". This term occurs, for example, in the Book of Joshua. It was used by people on the west side of the Jordan, including the biblical writers, to refer to the other side of the Jordan River. In the Septuagint, the is translated to translit. péran toú Jordánou,. The term was translated to lit=beyond the Jordan in the Vulgate Bible. However some authors give the, as the basis for Transjordan, which is also the modern Hebrew usage. The prefix is Latin and means "across" or beyond, so "Transjordan" refers to the land on the other side of the Jordan River. The equivalent Latin term for the west side is the Cisjordan - literally, "on this side of the Jordan". The term "East", as in "towards the sunrise", is also used in translit=Sharq al ʾUrdun.
Transjordanian tribes
The Book of Numbers tells how the tribes of Reuben and Gad came to Moses to ask if they could settle “beyond the Jordan”. Moses was dubious, but the two tribes promise to join in the conquest of the land, and so Moses grants them this region to live in. The half tribe of Manasseh are not mentioned until verse 33. David Jobling suggests that this is because Manasseh settled in land which previously belonged to Og, north of the Jabbok, while Reuben and Gad settled Sihon's land, which lay south of the Jabbok. Since Og's territory was not on the route to Canaan, it was "more naturally part of the Promised Land", and so the Manassites' status is less problematic than that of the Reubenites or Gadites. In the Book of Joshua, Joshua affirms Moses' decision, and urges the men of the two and a half tribes to help in the conquest, which they are willing to do. In Joshua 22, the Transjordanian tribes return, and build a massive altar by the Jordan. This causes the "whole congregation of the Israelites" to prepare for war, but they first send a delegation to the Transjordanian tribes, accusing them of making God angry and suggesting that their land may be unclean. In response to this, the Transjordanian tribes say that the altar is not for offerings, but is only a "witness". The western tribes are satisfied, and return home. Assis argues that the unusual dimensions of the altar suggest that it "was not meant for sacrificial use," but was, in fact, "meant to attract the attention of the other tribes" and provoke a reaction. Per the settlement of the Israelite tribes east of the Jordan, Burton MacDonald notes;
There are various traditions behind the Books of Numbers, Deuteronomy, Joshua, Judges, and 1 Chronicles’ assignment of tribal territories and towns to Reuben, Gad, and the half-tribe of Manasseh. Some of these traditions provide only an idealized picture of Israelite possessions east of the Jordan; others are no more than vague generalizations. Num 21.21–35, for example, says only that the land the people occupied extended from Wadi Arnon to Wadi Jabbok, the boundary of the Amorites.
Status
There is some ambiguity about the status of the Transjordan in the mind of the biblical writers. Horst Seebass argues that in Numbers "one finds awareness of Transjordan as being holy to YHWH." He argues for this on the basis of the presence of the cities of refuge there, and because land taken in a holy war is always holy. Richard Hess, on the other hand, asserts that "the Transjordanian tribes were not in the land of promise." Moshe Weinfeld argues that in the Book of Joshua, the Jordan is portrayed as "a barrier to the promised land," but in Deuteronomy and, the Transjordan is an "integral part of the promised land." Unlike the other tribal allotments, the Transjordanian territory was not divided by lot. Jacob Milgrom suggests that it is assigned by Moses rather than by God. Lori Rowlett argues that in the Book of Joshua, the Transjordanian tribes function as the inverse of the Gibeonites. Whereas the former have the right ethnicity, but wrong geographical location, the latter have the wrong ethnicity, but are "within the boundary of the 'pure' geographical location."
Other Transjordanian nations
According to the Hebrew Bible, Ammon and Moab were nations that occupied parts of Transjordan in ancient times. According to Genesis,, Ammon and Moab were descendants of Lot by Lot's two daughters, in the aftermath of the destruction of Sodom and Gomorrah. The Bible refers to both the Ammonites and Moabites as the "children of Lot", which may also translate as “descendants of Lot”. Throughout the Bible, the Ammonites and Israelites are portrayed as mutual antagonists. During the Exodus, the Israelites were prohibited by the Ammonites from passing through their lands. In the Book of Judges, the Ammonites work with Eglon, king of the Moabites against Israel. Attacks by the Ammonites on Israelite communities east of the Jordan were the impetus behind the unification of the tribes under Saul. According to both Books of Kings and Books of Chronicles, Naamah was an Ammonite. She was the only wife of King Solomon to be mentioned by name in the Tanakh as having borne a child. She was the mother of Solomon's successor, Rehoboam. The Ammonites presented a serious problem to the Pharisees because many marriages with Ammonite wives had taken place in the days of Nehemiah. The men had married women of the various nations without conversion, which made the children not Jewish. The legitimacy of David's claim to royalty was disputed on account of his descent from Ruth, the Moabite. King David spent time in the Transjordan after he had fled from the rebellion of his son Absalom.
