Jamieson, Fausset and Brown on 2 Chronicles 26:2

2. He built Eloth--or, "He it was who built Eloth." The account of the fortifications of this port on the Red Sea, which Uzziah restored to the kingdom of Judah (2Ch 33:13), is placed before the chronological notices (2Ch 26:3), either on account of the importance attached to the conquest of Eloth, or from the desire of the historian to introduce Uzziah as the king, who was known as the conqueror of Eloth. Besides, it indicates that the conquest occurred in the early part of his reign, that it was important as a port, and that Hebrew merchants maintained the old trade between it and the countries of the East [Bertheau].
