Passage
And I will add fifteen years to your life, and I will deliver you and this city from the hand of the king of Assyria; and I will defend this city for My own sake and for My servant David’s sake.”’”
And I will add fifteen years to your life, and I will deliver you and this city from the hand of the king of Assyria; and I will defend this city for My own sake and for My servant David’s sake.”’”
2 Kings 20:4 Now it happened that Isaiah had not gone out of the middle court, and the word of Yahweh came to him, saying,
2 Kings 20:5 “Return and say to Hezekiah the ruler of My people, ‘Thus says Yahweh, the God of your father David, “I have heard your prayer, I have seen your tears; behold, I will heal you. On the third day you shall go up to the house of Yahweh.
2 Kings 20:6 And I will add fifteen years to your life, and I will deliver you and this city from the hand of the king of Assyria; and I will defend this city for My own sake and for My servant David’s sake.”’”
2 Kings 20:7 Then Isaiah said, “Take a cake of figs.” And they took and laid it on the boil, and he was restored to life.
2 Kings 20:8 Now Hezekiah said to Isaiah, “What will be the sign that Yahweh will heal me, and that I shall go up to the house of Yahweh the third day?”
The verse centers on "fifteen", "years", "life", "deliver", "city", "hand", "king", and "assyria". It is saying that the verse draws attention to "fifteen" and "years", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "Return and say to Hezekiah the ruler..." into verse 7's "Then Isaiah said Take a cake of...", so "fifteen" and "years" belong inside that flow. In 2 Kings context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "fifteen" and "years" with trust shaped by these words, not by a vague optimism outside the passage.
