Lydia - This place is not well known. The Ludim were contiguous to Egypt, Genesis 11:13.
Chub - The Cubians, placed by Ptolemy in the Mareotis. But probably instead of וכוב vechub, "and Chub," we should read וכל vechol, "and All the men of the land," etc. The Septuagint adds "the Persians and the Cretans."
Libya, and Lydia - Or, as in Ezekiel 27:10, Phut and Lud.
The mingled people - Foreigners, who settled in Egypt. The Saite dynasty of Egyptian kings were especially favorable to foreign immigrants. Hophra employed many of them in his armies, and in this way, according to Herodotus, lost the affections of his Egyptian subjects. See Jeremiah 25:20 note.
Chub - The word occurs here only. It was some tribe in alliance with Egypt, either of African race like Lud and Phut, or settlers like the “mingled people.” A not-improbable suggestion connects it with Coptos of which the Egyptian form was Qeb Qebt or Qabt The men of the land that is in league - Rather, the children of the land of the covenant, i. e., of Israel (see Ezekiel 16:8). After the destruction of Jerusalem Jews withdrew into Egypt Jeremiah 43:7. Many of them would naturally enough be found in the Egyptian armies. This is in favor of the later date assigned to this section.
