Isaiah 38:2-5b, 16-19 So, Hezekiah cried bitterly for the Lord to spare his life and so He did by adding 15 years to his life. Hezekiah wrote in praise to the Lord for adding 15 more years to his life and saving his people from the hands of the Assyrian king. When we cry in humility the Lord sees our vulnerability and our fragility and so he does the unheard he adds life to our weak bones.
