Genealogies often pause and rewind to highlight the unexpected triumphs of specific family lines. In this family record, the focus shifts back to a previously mentioned wife of Shaharaim, Hushim, to detail her offspring. The primary approach among commentators is that the narrative intentionally returns to her to resume the account of her descendants. This happens either because the family line was temporarily interrupted to list the children of his other wife, Hodesh [רש״י], or to show that Hushim's children were born at a later time [מלבי״ם].
Beyond simply maintaining the order of the family tree, there is a deeper reason for highlighting these specific children. The narrative focuses on them to show that descendants who are distanced or rejected often rise to achieve incredible success. This was exactly the case for Hushim's lineage. Her family line reached major milestones, with her sons building entire cities and successfully driving out the inhabitants of Gath [רלב״ג].
