Isaiah 38:5 YLT

³  and saith, 'I pray thee, O Jehovah, remember, I pray Thee, how I have walked habitually before Thee in truth, and with a perfect heart, and that which 'is' good in thine eyes I have done;' and Hezekiah weepeth -- a great weeping.

⁴  And a word of Jehovah is unto Isaiah, saying,

⁵  Go, and thou hast said to Hezekiah, Thus said Jehovah, God of David thy father, 'I have heard thy prayer, I have seen thy tear, lo, I am adding to thy days fifteen years,

⁶  and out of the hand of the king of Asshur I deliver thee and this city, and have covered over this city.

⁷  And this 'is' to thee the sign from Jehovah, that Jehovah doth this thing that He hath spoken.
