Isaiah is instructed to go see the king, Ahaz. He is also instructed to take his son, Shearjashub.
The sons name means ‘a remnant shall return.’
Fullers field is uncertain today as to what it was, but as Isaiah mentions it, it must have been a well-known and public place in his day. The highway is a reference to a public travel-way or path that was likely heavily traveled.
The conduit and upper pool are references to water sources that feed the city of Jerusalem.
Various references to these locations are mentioned in 2 Kg 18:17; Isa 36:2; our passage Isa. 7:3; 2 Chron. 32:4, 30; Isa. 22:9.
Since the city was expecting an attack and siege, then this is likely why Ahaz was at the upper pool, conducting an inspection and probably discussing what could be done to retain a water source for the city and even prevent the enemy from using the water source during a siege.
Also, it is likely that since this is a public place, there would also be quite a crowd on hand as the king was there doing his business. Royalty always attracts a crowd. It would also seem reasonable to assume that many advisors in various capacities would be present, too.
And so, it is under these circumstances that Isaiah is instructed to go to the king, and more than that, he is instructed to bring his son along. His son’s name is in bold view here in this verse.
An attacked is expected, the cities survival is being investigated, and along comes Isaiah with his son whose name means ‘a remnant will return.’
The king and the public, whoever is present, have their eyes on water. Isaiah has his eyes on God and Gods promise.
The king is trying to figure out survival. Gods message guarantees survival. But survival will come at a price.
The people are not looking at God, but at their earthly resources, thus the reason of their predicament. Ahaz, in normal times should have been inspecting the military, which does not seem to be in existence, therefore the defense focuses on water, their use of it and the enemies lack of access to it.
But despite the spiritually negative attitude of the people in general, Isaiah will deliver Gods message of survival.
