2 Chronicles 32

27-29. he had exceeding much riches and honour--(compare 2 Kings 20:13 , Isaiah 39:2 ). A great portion of his personal wealth, like that of David and Uzziah, consisted in immense possessions of agricultural and pastoral produce. Besides, he had accumulated large treasures in gold, silver, and precious things, which he had taken as spoils from the Philistines, and which he had received as presents from neighboring states, among which he was held in great honor as a king under the special protection of Heaven. Much of his great wealth he expended in improving his capital, erecting forts, and promoting the internal benefit of his kingdom.

30. stopped the . . . watercourse of Gihon, and brought it . . . to the west side of the city--(Compare 2 Kings 20:20 ). Particular notice is here taken of the aqueduct, as among the greatest of Hezekiah's works. "In exploring the subterranean channel conveying the water from Virgin's Fount to Siloam, I discovered a similar channel entering from the north, a few yards from its commencement; and on tracing it up near the Mugrabin gate, where it became so choked with rubbish that it could be traversed no farther, I there found it turn to the west in the direction of the south end of the cleft, or saddle, of Zion, and if this channel was not constructed for the purpose of conveying the waters of Hezekiah's aqueduct, I am unable to suggest any purpose to which it could have been applied. Perhaps the reason why it was not brought down on the Zion side, was that Zion was already well-watered in its lower portion by the Great Pool, 'the lower pool of Gihon.' And accordingly WILLIAMS [Holy City] renders this passage, 'He stopped the upper outflow of the waters of Gihon, and led them down westward to the city'" [BARCLAY, City of the Great King]. The construction of this aqueduct required not only masonic but engineering skill; for the passage was bored through a continuous mass of rock. Hezekiah's pool or reservoir made to receive the water within the northwest part of the city still remains. It is an oblong quadrangular tank, two hundred forty feet in length, from one hundred forty-four to one hundred fifty in breadth, but, from recent excavations, appears to have extended somewhat farther towards the north.

31. in the business of the ambassadors who sent . . . to inquire of the wonder that was done in the land, &c.--They brought a present ( 2 Chronicles 32:23 ; and a letter of congratulation on his recovery, in which particular enquiries were made about the miracle of the sun's retrocession--a natural phenomenon that could not fail to excite great interest and curiosity at Babylon, where astronomy was so much studied. At the same time, there is reason to believe that they proposed a defensive league against the Assyrians.
God left him, to try him, &c.--Hezekiah's offense was not so much in the display of his military stores and treasures, as in not giving to God the glory both of the miracle and of his recovery, and thus leading those heathen ambassadors to know Him.
