Before Isaiah had left the middle court, the word of the Lord came to him: “Go back and tell Hezekiah, the leader of my people, ‘This is what the Lord, the God of your father David, says: I have heard your prayer and seen your tears; I will heal you. On the third day from now you will go up to the temple of the Lord. I will add fifteen years to your life. And I will deliver you and this city from the hand of the king of Assyria. I will defend this city for my sake and for the sake of my servant David.’” 2 Kings 20:4-6
Miraculously, the LORD added 15 years to Hezekiah’s life, plus he would be victorious over Assyria. Why? For the sake of David. Throughout the line of kings, the LORD never forgot David. The Bible says that the LORD had heard Hezekiah’s prayer and saw his tears.
This is not a devotional about answered or unanswered prayer or whether God keeps a record of all the tears you shed on the behalf of others. It has to do with God’s promises. God made a binding covenant with David. What was the essence of that covenant?
I will establish your seed forever And build up your throne to all generations.” Selah. Psalm 89:4
So, when we see references to “for the sake of my servant David,” we need to realize that He did it for OUR benefit too. Jesus Christ was in the lineage of David.
Take time to praise Him for having mercy on us in this way.
