Isaiah 38:15 is the response of King Hezekiah after God extends his life by fifteen years and heals him from a deadly illness. He admits he has no fitting words for what God has done, and he resolves to live slowly, humbly and thoughtfully for the rest of his days because of the deep distress he has been through. The words are spoken by Hezekiah himself, recorded in the first person as part of his prayer of thanks, and they are addressed to the Lord who has rescued him.
What will I say? He has both spoken to me, and himself has done it. I will walk carefully all my years because of the anguish of my soul.

What Isaiah 38:15 Means
The verse opens with a question, “What will I say?”, which is the admission of a man who has run out of words. Hezekiah is not being poetic here. He is overwhelmed, aware that a rescue this complete calls for more than a routine thank-you. The second half of the first sentence explains the reason for his speechlessness: God has both spoken the word of mercy and carried out the act of mercy himself. Hezekiah had been told he would die, and now the promise and the healing have come from the same hand.
The final clause shifts from gratitude to resolve. “I will walk carefully all my years” means he intends to live with humility and attentiveness, not carelessly. The phrase “because of the anguish of my soul” ties that resolve to what he has suffered, so the verse is about carrying forward the lessons of a hard season rather than forgetting them. The verse does not promise that Hezekiah will never sin again or that every later year will be trouble-free. It describes a heart shaped by a near brush with death and a settled intention to honor God with the time that remains.
The Context of Isaiah 38:15
The book of Isaiah is a collection of prophecies and narratives attributed to the prophet Isaiah, who ministered in Jerusalem during the late eighth century BC. Chapters 36 to 39 form a historical section that records events from the reign of King Hezekiah, including the threat of the Assyrian army and Hezekiah’s sickness. The original audience would have known the story of a king who turned to God in crisis and was answered, and the book itself was preserved for the people of Judah and later readers of Scripture.
Just before verse 15, Hezekiah describes his illness in vivid images: a shepherd’s tent pulled away, a weaver cutting thread from the loom, a lion breaking bones. He is at the edge of despair. Verses 16 to 17 then pivot to life and deliverance, saying that God has restored him and delivered his soul from the pit. Read in this setting, verse 15 is the hinge between the description of suffering and the celebration of rescue. It shows that Hezekiah’s silence and his promise to walk carefully both grow out of a near-death experience that he now sees as the Lord’s work.

A Short Prayer From Isaiah 38:15
Lord, like Hezekiah, I often find myself without the right words when you have been good to me. Help me to be honest about that, and to let silence be a form of worship when language falls short. Thank you for the times you have spoken and then acted, keeping your promises when I could not see how.
Teach me to walk carefully with the days you give me, mindful of what is precious and what is fragile. Let the hard seasons I have known shape my heart toward humility and attentiveness rather than carelessness. Amen.
