Go, and say to Hezekiah, Thus saith the LORD, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will add unto thy days fifteen years.
The God of David thy father. God remembers the covenant with the father to the children (Exodus 20:6; Psalms 89:28-29).
I have seen thy tears - (Psalms 56:8.)
I will add unto thy days fifteen years. Man's years, however many (as those of Methuselah), are but as so many days (Genesis 5:27).
