Later, the Lord sent this message to King Ahaz: “Ask the Lord your God for a sign of confirmation, Ahaz. Make it as difficult as you want—as high as heaven or as deep as the place of the dead.”
But the king refused. “No,” he said, “I will not test the Lord like that.”
Then Isaiah said, “Listen well, you royal family of David! Isn’t it enough to exhaust human patience? Must you exhaust the patience of my God as well? All right then, the Lord himself will give you the sign. Look! The virgin will conceive a child! She will give birth to a son and will call him Immanuel (which means ‘God is with us’). By the time this child is old enough to choose what is right and reject what is wrong, he will be eating yogurt and honey. For before the child is that old, the lands of the two kings you fear so much will both be deserted.” (Isaiah 7:10-16)
The year was 734 b.c. Ahaz, king of Judah in Jerusalem, was about to be attacked by an alliance of the northern kingdom of Israel and Aram. He was frightened by the possible end of his reign and by the invading armies who killed many people or took them as captives (2 Chronicles 28:5-21). But, as Isaiah predicted, the kingdom of Judah did not come to an end at this time. The sign of Immanuel would be a sign of deliverance.
This prophecy undoubtedly had a double fulfillment. (1) A young woman from the house of Ahaz who was not married would marry and have a son. Before three years passed (one year for pregnancy and two for the child to be old enough to talk), the two invading kings would be destroyed. (2) Matthew 1:23 quotes Isaiah 7:14 to show a further fulfillment of this prophecy in that a virgin named Mary conceived and bore a son, Immanuel, the Christ.
Ahaz appeared righteous by saying he would not test God with a sign. (“I will not test the Lord like that.”) In fact, God had told him to ask, but Ahaz didn’t really want to know what God would say. Sometimes we might use an excuse, such as not wanting to bother God, to keep us from communicating with him. Don’t let anything keep you from hearing and obeying God.
