17 Behold, [it was] for [my] peace [that] I had great bitterness: But thou hast in love to my soul delivered it from the pit of corruption; For thou hast cast all my sins behind thy back. 18 For Sheol cannot praise thee, death cannot celebrate thee: They that go down into the pit cannot hope for thy truth. 19 The living, the living, he shall praise thee, as I do this day: The father to the children shall make known thy truth. 20 Jehovah is [ready] to save me: Therefore we will sing my songs with stringed instruments All the days of our life in the house of Jehovah.

Matthew Henry's Commentary on Isaiah 38:17-20

Commentary on Isaiah 38:9-22

(Read Isaiah 38:9-22)

We have here Hezekiah's thanksgiving. It is well for us to remember the mercies we receive in sickness. Hezekiah records the condition he was in. He dwells upon this; I shall no more see the Lord. A good man wishes not to live for any other end than that he may serve God, and have communion with him. Our present residence is like that of a shepherd in his hut, a poor, mean, and cold lodging, and with a trust committed to our charge, as the shepherd has. Our days are compared to the weaver's shuttle, Job 7:6, passing and repassing very swiftly, every throw leaving a thread behind it; and when finished, the piece is cut off, taken out of the loom, and showed to our Master to be judged of. A good man, when his life is cut off, his cares and fatigues are cut off with it, and he rests from his labours. But our times are in God's hand; he has appointed what shall be the length of the piece. When sick, we are very apt to calculate our time, but are still at uncertainty. It should be more our care how we shall get safe to another world. And the more we taste of the loving-kindness of God, the more will our hearts love him, and live to him. It was in love to our poor perishing souls that Christ delivered them. The pardon does not make the sin not to have been sin, but not to be punished as it deserves. It is pleasant to think of our recoveries from sickness, when we see them flowing from the pardon of sin. Hezekiah's opportunity to glorify God in this world, he made the business, and pleasure, and end of life. Being recovered, he resolves to abound in praising and serving God. God's promises are not to do away, but to quicken and encourage the use of means. Life and health are given that we may glorify God and do good.
