Probably the same as Lud (2) (comp. Gen. 10:13; 1 Chr. 1:11). They are associated (Jer. 46:9) with African nations as mercenaries of the king of Egypt.
Ludim
Ludim appears in the family record that follows the flood: “Mizraim begat Ludim,” a son in the line of Ham. Later writers mention a people named Lud or Lydians who “handle and bend the bow” in Jeremiah, and who fight as soldiers for Tyre in Ezekiel. Isaiah lists Lud among distant nations that will hear of God’s glory. Scholars are not certain how every name links to a known people, and the text does not settle it. What the passages share is a picture of far-off nations that still belong to God’s concern. Genesis 10 is the starting point.

Isaiah
And I will set a sign among them, and I will send those that escape of them unto the nations, to Tarshish, Pul, and Lud, that draw the bow, to Tubal, and Javan, to the isles afar off, that have not heard my fame, neither have seen my glory; and they shall declare my glory among the Gentiles.
Jeremiah
Come up, ye horses; and rage, ye chariots; and let the mighty men come forth; the Ethiopians and the Libyans, that handle the shield; and the Lydians, that handle and bend the bow.
Ezekiel
They of Persia and of Lud and of Phut were in thine army, thy men of war: they hanged the shield and helmet in thee; they set forth thy comeliness.
Ethiopia, and Libya, and Lydia, and all the mingled people, and Chub, and the men of the land that is in league, shall fall with them by the sword.
