Senate
The English word "senate" carries the older sense of a body of elders. Within UPDV scope, the umbrella resolves to a single line in the Psalter that names the elders of Pharaoh's court alongside his princes, set within the larger remembrance of how Joseph's God-given wisdom turned a foreign court.
Princes and Elders
The remembrance of Joseph's elevation in Egypt names the two ranks at the top of Pharaoh's court — princes and elders — and credits the rise to a divine purpose: "To bind his princes in his soul, / And teach his elders wisdom" (Ps 105:22).
The line places the council of elders in parallel with the princes, identifying them as the body whose instruction Joseph was set over. Within UPDV vocabulary, "elders" is the class the umbrella term gathers — the elder-council that, in older English usage, the word "senate" names.
