Out of that land went forth Asshur, and builded Nineveh, and the city Rehoboth, and Calah, Out of that land went forth Asshur - The marginal reading is to be preferred here. He - Nimrod, went out into Assyria and built Nineveh; and hence Assyria is called the land of Nimrod, Micah 5:6. Thus did this mighty hunter extend his dominions in every possible way. The city of Nineveh, the capital of Assyria, is supposed to have had its name from Ninus, the son of Nimrod; but probably Ninus and Nimrod are the same person. This city, which made so conspicuous a figure in the history of the world, is now called Mossul; it is an inconsiderable place, built out of the ruins of the ancient Nineveh.
Rehoboth, and Calah, etc. - Nothing certain is known concerning the situation of these places; conjecture is endless, and it has been amply indulged by learned men in seeking for Rehoboth in the Birtha of Ptolemy, Calah in Calachine, Resen in Larissa, etc., etc.
