Iordanes is the named river or surrounding locality used for baptisms, travel, and descriptions of regions across or around it.

The occurrences identify a named river as the setting for baptism and as a point of departure or destination; they also use it to locate regions as around, across, or beyond the river. The genitive singular form predominates in these relational place descriptions, while dative and accusative forms occur where the verse presents baptism in or movement toward the river.

   The dative form marks the location of baptisms in Mark 1:5 and Matthew 3:6; in Mark 1:9 and Matthew 3:13, the accusative form occurs in clauses describing Jesus coming to and being baptized there. In Luke 4:1 the APB renders Jesus as returning "from the Jordan," while Luke 3:3 places preaching in the region around it.

2. A geographic boundary or regional locator · common

   The genitive form occurs with descriptions of places on the other side, beyond, or around the river. In Matthew 19:1 the APB renders arrival in Judea "beyond the Jordan," and in John 10:40 it renders movement "to the other side of the Jordan."

In the Anselm Project Bible: The APB usually presents the name as "the Jordan" or "the Jordan River." It also incorporates it into location phrases such as "across the Jordan," "beyond the Jordan," and "the region around the Jordan"; these are verse-level renderings, not definitions.
