In those days was Hezekiah sick unto death. And the prophet Isaiah the son of Amoz came to him, and said unto him, Thus saith the LORD, Set thine house in order; for thou shalt die, and not live.

Wesley's Notes

20:1 Those days - In the year of the Assyrian invasion. Set, and c. - Make thy will, and settle the affairs of thy family and kingdom. Not live - Such threatenings, though absolutely expressed, have often secret conditions.

King James Translators' Notes

Set...: Heb. Give charge concerning thine house

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 20

2Ki 20:1-7. Hezekiah's Life Lengthened.

1. In those days was Hezekiah sick-As his reign lasted twenty-nine years (2Ki 18:2), and his kingdom was invaded in the fourteenth (2Ki 18:13), it is evident that this sudden and severe illness must have occurred in the very year of the Syrian invasion. Between the threatened attack and the actual appearance of the enemy, this incident in Hezekiah's history must have taken place. But according to the usage of the sacred historian, the story of Sennacherib is completed before entering on what was personal to the king of Judah (see also Isa 37:36-38:1).

Set thine house in order-Isaiah, being of the blood royal, might have access to the king's private house. But since the prophet was commissioned to make this announcement, the message must be considered as referring to matters of higher importance than the settlement of the king's domestic and private affairs. It must have related chiefly to the state of his kingdom, he having not as yet any son (compare 2Ki 20:6 with 2Ki 21:1).

for thou shall die, and not live-The disease was of a malignant character and would be mortal in its effects, unless the healing power of God should miraculously interpose.

Matthew Henry's Concise Commentary

20:1-11 Hezekiah was sick unto death, in the same year in which the king of Assyria besieged Jerusalem. A warning to prepare for death was brought to Hezekiah by Isaiah. Prayer is one of the best preparations for death, because by it we fetch in strength and grace from God, to enable us to finish well. He wept sorely: some gather from hence that he was unwilling to die; it is in the nature of man to dread the separation of soul and body. There was also something peculiar in Hezekiah's case; he was now in the midst of his usefulness. Let Hezekiah's prayer, see Isa 38. interpret his tears; in that is nothing which is like his having been under that fear of death, which has bondage or torment. Hezekiah's piety made his sick-bed easy. O Lord, remember now; he does not speak as if God needed to be put in mind of any thing by us; nor, as if the reward might be demanded as due; it is Christ's righteousness only that is the purchase of mercy and grace. Hezekiah does not pray, Lord, spare me; but, Lord, remember me; whether I live or die, let me be thine. God always hears the prayers of the broken in heart, and will give health, length of days, and temporal deliverances, as much and as long as is truly good for them. Means were to be used for Hezekiah's recovery; yet, considering to what a height the disease was come, and how suddenly it was checked, the cure was miraculous. It is our duty, when sick, to use such means as are proper to help nature, else we do not trust God, but tempt him. For the confirmation of his faith, the shadow of the sun was carried back, and the light was continued longer than usual, in a miraculous manner. This work of wonder shows the power of God in heaven as well as on earth, the great notice he takes of prayer, and the great favour he bears to his chosen.
