Then Yahweh said to Isaiah, “Go out now to meet Ahaz, you and Shear-jashuba your son, at the end of the channel from the upper pool on the highway to the Launderer’s Field. Bible other translations
The name means “A remnant will return.”

“Shear-jashub.” The meaning of Shear-jashub is “a remnant will return.” The reason that Isaiah was told to bring his son is not stated. It is possible that God wanted there to be two witnesses to what Isaiah told the king, although the king would certainly not have been alone with Isaiah. But it is also possible that the prophetic meaning of Shear-jashub was important, even if ambiguous. The meaning could be taken in a negative sense, that the devastation of Judah would be so great that only a remnant would be left to return, or it could be taken positively, that no matter how great the destruction was, there would be a remnant left to return to work and even return to God. There is no indication in the text that Ahaz paid any attention to Shear-jashub, and as we learn in the text, Ahaz had already hired the Assyrians to attack Syria and Israel, so he likely did not think much at all about what Isaiah said.

“upper pool.” As the population of Jerusalem grew and expanded north from its only natural water source, the Gihon Spring, aqueducts and huge cisterns were needed to provide water for the population. Today there are huge pools outside of Jerusalem that used to supply water to the city, but although they are called “Solomon’s pools,” Solomon did not build them.
