In our study of Isaiah chapter seven, we look at God's promise to preserve a portion of His people. In this chapter, we see a beautiful prophecy and picture of the coming of the Lord Jesus.
"When Ahaz son of Jotham, the son of Uzziah, was king of Judah, King Rezin of Aram and Pekah son of Remaliah king of Israel marched up to fight against Jerusalem, but they could not overpower it." NIV translation
The chapter opens with a civil war that is happening between God's people. We see that not only did Syria (Aram) attack Jerusalem but the northern kingdom of God's people (Israel) had tried to take the city but failed. We are also told that this happened during the reign of Ahaz in Jerusalem. Although his father, Jotham, had been a good king, Ahaz turned away from the ways of God and was a very bad king.
"Now the house of David was told, 'Aram has allied itself with Ephraim'; so the hearts of Ahaz and his people were shaken, as the trees of the forest are shaken by the wind." NIV translation
Now, the king is informed that the two (Syria & Israel) have joined together to attack the city.
We are told that the king and the people were afraid as they had withstood the individual attacks but now they faced a combined attack. Since Ahaz had turned away from God in disobedience, he did not expect God to bless them and to fight for them.
"Then the Lord said to Isaiah, 'Go out, you and your son Shear-Jashub, to meet Ahaz at the end of the aqueduct of the Upper Pool, on the road to the Washerman's Field.'" NIV translation
Even though Ahaz did not deserve it, God sent Isaiah to him to bring him encouragement. It is interesting to note that God told Isaiah to take his son with him and that his son's name means "a remnant will return". The place God told him to meet Ahaz is significant as well. The aqueduct brought water into the city from the Upper Pool. The word upper comes from two words "most" and "high" and pool comes from the word "blessing".
This was a picture of the coming blessing from God Most High which is Jesus Christ. The Word of God is described throughout the Bible as water and Jesus is described as the Word in the opening of the book of John. We are also told that this was on the way to the Washerman's Field which is where the people did their laundry. This is a beautiful picture of the fact that Jesus cleans us from our sins. We, too, can be encouraged by the fact that our salvation (cleaning) does not depend on us but is freely flowing just as the water flowed into Jerusalem.
