Deuel
Deuel appears in the UPDV only as the father of Eliasaph, the man who stands at the head of the tribe of Gad through the wilderness organization of Numbers. He is never himself active on the page; the references all turn on his patronymic, which fixes Eliasaph's lineage as the camp is mustered, arrayed, brought to the dedication of the altar, and set in marching order.
Father of Eliasaph the prince of Gad
The first census names him at the moment the tribal heads are listed. Among the men appointed to stand with Moses and Aaron, the tribe of Gad is represented by "Eliasaph the son of Deuel" (Nu 1:14). The same identification is repeated when the camp is assigned its quarters around the tabernacle: "And the tribe of Gad: and the prince of the sons of Gad will be Eliasaph the son of Deuel" (Nu 2:14). The patronymic is the working identifier — Eliasaph is fixed in the record by reference to his father.
In the dedication of the altar
When the princes bring their offerings on successive days, Deuel surfaces twice in the Gadite block. The day's heading reads, "On the sixth day Eliasaph the son of Deuel, prince of the sons of Gad" (Nu 7:42), and the closing summary of the gifts ends, "this was the oblation of Eliasaph the son of Deuel" (Nu 7:47). The repetition frames the day's offering: opened and closed with Eliasaph's patronymic, with Deuel's name carrying the genealogical weight.
In the marching order
When the host is set in motion, the tribal commands are given in the same form. Over the Gadite division stood "Eliasaph the son of Deuel" (Nu 10:20). The pattern that began with the census carries through to the march: throughout these passages of Numbers Deuel functions as the line of descent through which the leader of Gad is identified.
