32:24-33 God left Hezekiah to himself, that, by this trial and his weakness in it, what was in his heart might be known; that he was not so perfect in grace as he thought he was. It is good for us to know ourselves, and our own weakness and sinfulness, that we may not be conceited, or self-confident, but may always live in dependence upon Divine grace. We know not the corruption of our own hearts, nor what we shall do if God leaves us to ourselves. His sin was, that his heart was lifted up. What need have great men, and good men, and useful men, to study their own infirmities and follies, and their obligations to free grace, that they may never think highly of themselves; but beg earnestly of God, that he will always keep them humble! Hezekiah made a bad return to God for his favours, by making even those favours the food and fuel of his pride. Let us shun the occasions of sin: let us avoid the company, the amusements, the books, yea, the very sights that may administer to sin. Let us commit ourselves continually to God's care and protection; and beg of him never to leave us nor forsake us. Blessed be God, death will soon end the believer's conflict; then pride and every sin will be abolished. He will no more be tempted to withhold the praise which belongs to the God of his salvation.
30. stopped the … watercourse of Gihon, and brought it … to the west side of the city, &c.—(Compare 2Ki 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.
