In the days of Ahaz son of Jotham son of Uzziah, king of Judah, King Rezin of Aram and King Pekah son of Remaliah of Israel went up to attack Jerusalem, but could not mount an attack against it.
When the house of David heard that Aram had allied itself with Ephraim, the heart of Ahaz and the heart of his people shook as the trees of the forest shake before the wind.
Then the LORD said to Isaiah, Go out to meet Ahaz, you and your son Shear-jashub, at the end of the conduit of the upper pool on the highway to the Fuller's Field,
and say to him, Take heed, be quiet, do not fear, and do not let your heart be faint because of these two smoldering stumps of firebrands, because of the fierce anger of Rezin and Aram and the son of Remaliah.
The LORD will bring on you and on your people and on your ancestral house such days as have not come since the day that Ephraim departed from Judah-- the king of Assyria."
On that day the Lord will shave with a razor hired beyond the River-- with the king of Assyria-- the head and the hair of the feet, and it will take off the beard as well.
and as for all the hills that used to be hoed with a hoe, you will not go there for fear of briers and thorns; but they will become a place where cattle are let loose and where sheep tread.
