When Hezekiah saw - This was in the fourteenth year of the reign of Hezekiah; and at first the Jewish king bought him off at the great price of three hundred talents of silver, and thirty talents of gold; and even emptied his own treasures, and spoiled the house of the Lord, to gratify the oppressive avarice of the Assyrian king. See the whole account, 2 Kings 18:13, etc.

And when Hezekiah saw that Sennacherib was come,.... Into the land of Judah, which he perceived and understood by reports brought to him: and that he was purposed to fight against Jerusalem; to besiege it and take it, if possible; this he saw was his design, by taking the fenced cities in his way, and coming forward with his forces.

Preparations of Hezekiah for the strengthening and defending of Jerusalem. - We find an account of this neither in 2 Kings 18 nor in Isaiah 36; but the fact is confirmed both by Isaiah 22:8-11, and by the remark 2 Kings 20:20 (cf. 2 Chronicles 32:30 of our chapter).

2 Chronicles 32:2-4

When Hezekiah saw that Sennacherib advanced, and his face was to war against Jerusalem, i.e., that he purposed to capture Jerusalem, he consulted with his princes and his valiant men to cover the waters of the springs which were outside the city; and they helped him, brought much people together, and covered all the springs, and the brook which ran through the midst of the land. סתם does not denote to obstruct, but only to hide by covering and conducting the water into subterranean channels. The brook which flowed through the midst of the land is the Gihon, which was formed by the waters flowing from the springs, and was dried up by these springs being covered and the water diverted. For further information, see on 2 Chronicles 32:30. The object of this measure is stated in the words which follow: Why should the kings of Assyria come and find much water? i.e., why should we provide them with much water, when they advance against the city and besiege it? The plural, kings of Assyria, is rhetorical, as in 2 Chronicles 28:16.

And when Hezekiah saw that Sennacherib was come, and that he was purposed to fight against Jerusalem,

he was...: Heb. his face was to war

2-8. when Hezekiah saw that Sennacherib . was purposed to fight against Jerusalem-An account of the means taken to fortify Jerusalem against the threatened siege is given only in this passage. The polluting or filling up of wells, and the altering of the course of rivers, is an old practice that still obtains in the wars of the East. Hezekiah's plan was to cover the fountain heads, so that they might not be discovered by the enemy, and to carry the water by subterranean channels or pipes into the city-a plan which, while it would secure a constant supply to the inhabitants, would distress the besiegers, as the country all around Jerusalem was very destitute of water.

32:1-23 Those who trust God with their safety, must use proper means, else they tempt him. God will provide, but so must we also. Hezekiah gathered his people together, and spake comfortably to them. A believing confidence in God, will raise us above the prevailing fear of man. Let the good subjects and soldiers of Jesus Christ, rest upon his word, and boldly say, Since God is for us, who can be against us? By the favour of God, enemies are lost, and friends gained.
