Parallel
Genesis 43:32
Brenton's English Septuagint · Berean Standard Bible
And they set on [bread] for him alone, and for them by themselves, and for the Egyptians feasting with him by themselves, for the Egyptians could not eat bread with the Hebrews, for it is an abomination to the Egyptians.
They separately served Joseph, his brothers, and the Egyptians. They ate separately because the Egyptians would not eat with the Hebrews, since that was detestable to them.
