What is the meaning of Isaiah 38:18?

Sheol cannot thank You

Hezekiah’s poem flows from relief after God added fifteen years to his life. By saying, “For Sheol cannot thank You,” he contrasts the living and the dead:

• Sheol is the realm of the departed. In that shadowy place there is no public, audible gratitude offered to God. Psalm 6:5 echoes, “For there is no mention of You in death; who can praise You from Sheol?”

• The statement is not a denial of life after death but a simple fact that thanksgiving is voiced on earth, not from the grave. Ecclesiastes 9:10 reminds us that “there is no work or planning or knowledge or wisdom in Sheol.”

• Hezekiah reasons that preserving his life allows continued testimony. Like Psalm 30:9 pleads, “Will the dust praise You? Will it proclaim Your faithfulness?” he wants more years to testify publicly to the Lord’s greatness.


Death cannot praise You

The next line intensifies the thought: “Death cannot praise You.”

• Praise in Scripture is an active, vibrant response. Psalm 115:17 observes, “It is not the dead who praise the LORD, nor any who descend into silence.”

• Hezekiah is not claiming that souls are extinguished; rather, once body and tongue are stilled, earthly praise meetings cease. Psalm 88:10-12 asks, “Do You work wonders for the dead? … Is Your loving devotion declared in the grave?”

• The verse also underlines how precious every breathing moment is for honoring God. Paul carries the idea forward in Philippians 1:20-21: living means fruitful labor and magnifying Christ, while death is gain—but only life lets us praise aloud before a watching world.


Those who descend to the Pit cannot hope for Your faithfulness

The “Pit” pictures the grave itself. Hezekiah adds a third layer: when a person slips below ground, there is no further expectation of experiencing God’s covenant acts in this present age.

• Jonah used the same word when he cried, “You raised my life from the pit, O LORD my God!” (Jonah 2:6), grateful for deliverance that restored his hope.

• For Hezekiah, being spared from the Pit meant seeing God’s “faithfulness” (ḥesed) in real time—watching Passover celebrations, leading reforms, telling the next generation. Psalm 88:4-5 laments, “I am counted among those who go down to the Pit … You remember them no more,” highlighting that earthly opportunities cease at burial.

• Yet Scripture also hints at ultimate triumph beyond the grave. Psalm 16:10 promises, “You will not abandon my soul to Sheol,” a prophecy fulfilled in Christ’s resurrection, assuring believers that God’s faithfulness ultimately pierces even the Pit.


summary

Isaiah 38:18 voices a life-and-death contrast: once a person enters the grave, he can no longer lift public thanks, shout praise, or experience fresh displays of God’s covenant love in this world. Hezekiah, freshly healed, treasures extended years so he can keep doing those very things. The verse urges us to seize every heartbeat for gratitude, praise, and testimony, confident that God’s faithfulness will outlast the grave yet eager to honor Him while we live.
