11 “Ask the LORD your God for a sign, whether in the deepest depths or in the highest heights.”
12 But Ahaz said, “I will not ask; I will not put the LORD to the test.”
13 Then Isaiah said, “Hear now, you house of David! Is it not enough to try the patience of humans? Will you try the patience of my God also?
14 Therefore the Lord himself will give youa a sign: The virginb will conceive and give birth to a son, andc will call him Immanuel.d
15 He will be eating curds and honey when he knows enough to reject the wrong and choose the right,
16 for before the boy knows enough to reject the wrong and choose the right, the land of the two kings you dread will be laid waste.
17 The LORD will bring on you and on your people and on the house of your father a time unlike any since Ephraim broke away from Judah—he will bring the king of Assyria.”

18 In that day the LORD will whistle for flies from the Nile delta in Egypt and for bees from the land of Assyria.
19 They will all come and settle in the steep ravines and in the crevices in the rocks, on all the thornbushes and at all the water holes.
20 In that day the Lord will use a razor hired from beyond the Euphrates River—the king of Assyria—to shave your heads and private parts, and to cut off your beards also.
21 In that day, a person will keep alive a young cow and two goats.
