Isaiah 38:4 WEB

²  Then Hezekiah turned his face to the wall, and prayed to Yahweh,

³  and said, Remember now, Yahweh, I beg you, how I have walked before you in truth and with a perfect heart, and have done that which is good in your sight. Hezekiah wept sore.

⁴  Then came the word of Yahweh to Isaiah, saying,

⁵  Go, and tell Hezekiah, Thus says Yahweh, the God of David your father, I have heard your prayer, I have seen your tears: behold, I will add to your days fifteen years.

⁶  I will deliver you and this city out of the hand of the king of Assyria; and I will defend this city.
