The entire household of Jacob—his wives, children, grandchildren, and possessions, including livestock and servants—migrated as one unit. Such an extensive understanding of "house" is substantiated by the book of Genesis, which emphasizes that "his sons and his sons' sons, and all his seed, his daughters and his daughters' daughters, came into Egypt with Jacob, and that they took their cattle and all their goods with them" (Gen. XLVI:6-7). Genesis also provides a detailed list of the members of Jacob's family who accompanied him into Egypt. Nevertheless, one must question the implication of them traveling with Jacob. Did they all journey with him personally? The answer is no, as Joseph had already settled in Egypt well before Jacob's migration. Additionally, some family members mentioned, including the children of Joseph—Ephraim and Manasseh (Gen. XLVI:27)—and the grandchildren from Judah and Benjamin, were born in Egypt. Therefore, when it states that those listed came with Jacob, it means that some accompanied him personally, while others were born either to him or Joseph during their lifetimes.
In total, there were said to be seventy-five souls that came from Jacob, referring to seventy-five members from his line who entered Egypt. However, the Hebrew text in Exodus, as well as in Genesis (XLVI:27) and Deuteronomy (X:22), records the figure as 70 souls, differing from the 75 found in the Greek and Slavonic versions of the Bible. This discrepancy resulted from Greek translators adding five individuals—Joseph's grandchildren—identified later in Numbers (XXVI:3) and in 1 Chronicles (VII:14), acknowledging Joseph’s crucial role in the migration narrative. The number 75 is reiterated in Stephen's address to the Hellenistic Jews, who were familiar with the Greek text (Acts VII:14).
In essence, the 75 represents the significant ancestors of Jacob's lineage. If we consider that this figure does not account for the wives and daughters of Jacob's sons, nor the servants, then the true number of those who settled in Egypt with Jacob, and those born there during his and Joseph's lifetimes, is indeed much greater.
