Charles Ellicott Commentary Isaiah 60:7

"All the flocks of Kedar shall be gathered together unto thee, the rams of Nebaioth shall minister unto thee; they shall come up with acceptance on mine altar; and I will glorify the house of my glory." — Isaiah 60:7 (ASV)

Kedar. —The nomad tribes (Isaiah 21:17) come as well as the trading ones. Nebaioth, mentioned with Kedar, in Genesis 25:13, among the descendants of Ishmael, expanded in the centuries preceding the Christian era, into the kingdom of the Nabathœan Arabs, spreading from the Ælanitic Gulf to the Haurân. The two names together include what were known to the Roman geographers as Arabia Felix and Arabia Petræa. The primary thought is that the Temple of the new Jerusalem will be supplied with its sacrifices from the inexhaustible flocks of these regions.
