Isaiah 22:7

“And it shall come to pass, [that] thy choicest valleys, &c.] The valleys that were near Jerusalem, that used to be covered with the choicest corn or vines, or with grass and flocks of sheep, and used to be exceeding delightful and pleasant: shall be full of chariots; where they can be more easily driven than on mountains; these were chariots not for pleasure, but for war; chariots full of soldiers, to fight against and besiege Jerusalem: and the horsemen shall set themselves in array at the gate: to take them that come out of the city, and to force their way into it; as well as to protect and defend the foot, while they made the assault, and scaled the walls, and to be ready when the gates…”

“Thy choicest valleys - Hebrew, ‘The choice of thy galleys;’ meaning the most fertile and most valued lands in the vicinity of the city. The rich and fertile vales around Jerusalem would be occupied by the armies of the Assyrian monarch. What occurs in this verse and the following verses to Isaiah 22:14, is a prophetic description of what is presented historically in Isaiah 36:0, and 2 Chronicles 32:0.

Set themselves in array - Hebrew, ‘Placing shall place themselves;’ that is, they shall be drawn up for battle; they shall besiege the city, and guard it…”

“Valleys - Valleys were the most proper places for the use of chariots. Gate - To assist the footmen while they made their assault, and to prevent those who endeavoured to escape. Isaiah 22:8”

“22:7 The Kidron and Hinnom valleys were located to the east and south of Jerusalem.”

“thy choicest valleys: Heb. the choice of thy valleys full: Isa 8:7, Isa 8:8, Isa 10:28-32, Isa 37:34; Jer 39:1-3 at: or, toward Isaiah 22:8”
