Then said the LORD unto Isaiah, Go forth now to meet Ahaz, thou, and Shearjashub thy son, at the end of the conduit of the upper pool in the highway of the fuller's field;
Ver. 3. Then said the Lord unto Isaiah.] Wicked Ahaz shall have a prophet sent him with a promise, if it be but to leave him without excuse. There was also a godly party in the land, whose comfort was aimed at, and for whose sake Shearjashub was also taken along, as carrying comfort in this very name. Portendit enim omnes pios qui divini verbi satu generandi sunt salvos et incolumes fore, divinisque muneribus exornatos.
At the end of the conduit of the upper pool.] Where he is walking and talking about sending to Assyria for help. The place is pointed out for confirmation of the truth of the prophecy. So in the gospel the apostles are foretold where to fetch the ass, where to prepare the passover. This place was without the city, opposite the royal palace, the very same where afterwards Rabshakeh (the fugitive son of our prophet Isaiah, say the Rabbis, but without reason), railed upon the living God. This prophecy here and now delivered, might haply be some support to good Hezekiah under that trial. 2Ki 18:13-37
Of the fuller's field.] Fullers must have store of water, and room enough for the dressing and drying of their clothes. Ministers are by an ancient called Fullones animarum, Fullers of men's souls.
