Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

Reign of Jotham of Judah (cf. Ch2 27:1-9). - Kg2 15:32. "In the second year of Pekah Jotham began to reign." This agrees with the statement in Kg2 15:27, that Pekah became king in the last year of Uzziah, supposing that it occurred at the commencement of the year. Jotham's sixteen years therefore came to a close in the seventeenth year of Pekah's reign (Kg2 16:1). His reign was like that of his father Uzziah (compare Kg2 15:34, Kg2 15:35 with Kg2 15:3, Kg2 15:4), except, as is added in Chr. Kg2 15:2, that he did not force himself into the temple of the Lord, as Uzziah had done (Ch2 26:16). All that is mentioned of his enterprises in the account before us is that he built the upper gate of the house of Jehovah, that is to say, that he restored it, or perhaps added to its beauty. The upper gate, according to Eze 9:2 compared with Kg2 8:3, Kg2 8:5,Kg2 8:14 and Kg2 8:16, is the gate at the north side of the inner or upper court, where all the sacrifices were slaughtered, according to Eze 40:38-43. We also find from Ch2 27:3. that he built against the wall of Ophel, and several cities in the mountains of Judah, and castles and towers in the forests, and subdued the Ammonites, so that they paid him tribute for three years. Jotham carried on with great vigour, therefore, the work which his father had began, to increase the material prosperity of his subjects.
