(5) The captain of my people.--Or, ruler (n?gid); a designation of honour (1Kings 1:35; 1Samuel 10:1). This is wanting in Isaiah 38, as well as the end of the verse "I will heal thee," &c. That narrative looks like an abbreviated transcript of the present, or of a common original.

On the third day.--Comp. Hosea 6:2. Here, however, there is no ground for understanding the expression other than literally. The precise nature of Hezekiah's malady cannot be ascertained.

Verse 5. - Turn again - or, turn back - "retrace thy steps, and enter once more into the bedchamber of the king" - and tell Hezekiah the captain of my people. An unusual title for the Jewish monarch, but one applied in 1 Samuel 9:16 and 1 Sam 10:1 to Saul, and in 1 Samuel 13:14 and 2 Samuel 5:2 to David. The proper meaning of נָגִיד is "leader" - "one who goes in front." Thus saith the Lord, the God of David thy father - Hezekiah obtains mercy, both as David's son and as David's imitator (see 2 Kings 18:3) - I have heard thy prayer, I have seen thy tears (comp. Exodus 2:24; Exodus 3:7; Psalm 56:8). There is not a cry, not a groan, not a tear, not a sigh of his faithful ones, to which the heart of God is not open, which does not touch him, move him, draw forth his sympathy. If he does not always grant our prayers, it is because we "ask amiss" - without faith, or without fervor, or things not good for us. Hezekiah's earnest, faithful, and not unwise prayer was, as such prayers always are, effectual. Behold, I will heal thee: on the third day thou shalt go up unto the house of the Lord; i.e. thou shalt be so completely recovered as to be able to quit thy palace and pay thy vows in the courts of the Lord's house. God knows that to do this will be Hezekiah's first wish, as soon as his sickness is past (comp. Isaiah 38:20).

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.Turn again, and tell Hezekiah the captain of my people,.... The king of them, as the Targum:

thus saith the Lord God of David thy father, I have heard thy prayer, I have seen thy tears; See Gill on Isaiah 38:5.

behold, I will heal thee; instantly, miraculously; and none but God could heal him, his disease being in its kind mortal, and he had been told from the Lord that he should die:

on the third day thou shalt go up unto the house of the Lord: the temple, to give thanks for his recovery; and this he should do on the third day from thence; so soon should he be well, which would show the cure to be miraculous.
