   In Numbers 1:20, the construct plural stands within the listing of Reuben's descendants by families, fathers' houses, and names for military enrollment. The same classification setting appears in Exodus 6:16, where Levi's sons are named, and in 1 Chronicles 7:9, where an enrollment is described in relation to fathers' houses.

In the Anselm Project Bible: The APB commonly presents the term with “generations,” both in introductory statements such as Genesis 11:27 and in classification formulas such as Numbers 1:20. Those English occurrences confirm the clauses' overall presentation rather than supplying a fixed individual-word rendering.
