Isaiah 38:3-6

ISV(i) 3 “Please, LORD,” he said, “Remember how I have walked before you faithfully and with a true heart, and I have done what pleases you.” And Hezekiah wept bitterly.
4 Then this message from the LORD came to Isaiah: 5 “Go tell Hezekiah, ‘This is what the LORD God of your ancestor David has to say: “I’ve heard your prayer and I’ve seen your tears; so I will add fifteen years to your life. 6 I’ll save you and this city from the king of Assyria, and I’ll defend this city, for my own sake and for my servant David’s sake.
