The strong shall be as tinder

a. The LORD of hosts, the Mighty One of Israel: God now addresses Judah, introducing Himself with titles showing His power and majesty. He is the LORD of hosts, “hosts” referring to the armies of heaven. He is the Mighty One of Israel, whom it is futile to oppose. The title itself is a wake-up call.

i. Bultema on the LORD of hosts: “Describes Him as the Warrior who has all the angels as mighty soldiers at His disposal in the battle against the wicked. This is God’s battle name and as a rule it signifies little good when He uses it in reference to His people, as is the case here. It usually implies that He considers and deals with His people as His enemies.”

b. I will rid Myself of My adversaries: The problem with the leaders and people of Judah was that they had set themselves as adversaries of the LORD. They were acting like His enemies. They were putting themselves in the path of judgment. They would find the hand of the LORD against them, instead of for them.

c. And thoroughly purge away your dross, and take away all your alloy: Dross and alloy are impurities in metal. God promised to “turn up the heat” and refine Judah, taking away their impurities. His goal was not to destroy; instead He says, “I will restore.” God will purify Jerusalem, to the point where Afterward you shall be called the city of righteousness, the faithful city.

d. Zion shall be redeemed with justice: God’s redemption and restoration are always done with justice and righteousness. He never saves or redeems at the expense of His justice and righteousness.

e. They shall be ashamed of the terebinth trees which you have desired: These terebinth trees were sites of pagan worship which idol-loving Judah kept among them. When Zion is redeemed with justice, they would be ashamed of their former idolatries.

i. It is good to be ashamed and embarrassed over sin. There is something wrong with us when we are shameless or beyond embarrassment. God promised He would give Judah the gift of shame and embarrassment over sin again.

ii. “Sacred trees played an important part in the Canaanite fertility cult…for deciduous trees like the oak or terebinth may well have symbolized the death and rebirth of the god. The ‘gardens’ may be groves of these trees, or, alternatively, places of sacred springs or wells.” (Grogan)

f. As a terebinth tree whose leaf fades…as a garden that has no water…. ..both will burn together: The LORD spoke here of the spiritual dryness of Judah. Though they continued their religious ritual and ceremony, they were still spiritually dry. And as dry trees, dry gardens, and dry tinder are ready to burn, so was an unrepentant Judah ready to feel the fires of God’s refining judgment.

ii. We know more about Isaiah than we do about many other of the prophets. Isaiah was married and was the father of at least two sons (Isaiah 7:3 and 8:3). He lived in Jerusalem (Isaiah 7:3, 22:1, 37:2, 38:5, and 39:3).

3. (5-9) The desperate condition of Judah.

a. You rulers of Sodom…you people of Gomorrah: God was obviously trying to get the attention of the leaders and people of Judah. He did this by associating them with two cities synonymous with sin and judgment.

de now: When we consider the greatness of God’s cleansing and pardon, it is all the more reason for us to come now. God wants the separation between you and He to be gone now. He doesn’t want you to continue in your destructive path another moment. He wants the best for us now.

Therefore the Lord says, The LORD of hosts, the Mighty One of Israel, “Ah, I will rid Myself of My adversaries, And take vengeance on My enemies. I will turn My hand against you, And thoroughly purge away your dross, And take away all your alloy. I will restore your judges as at the first, And your counselors as at the beginning. Afterward you shall be called the city of righteousness, the faithful city.” Zion shall be redeemed with justice, And her penitents with righteousness. The destruction of transgressors and of sinners shall be together, And those who forsake the LORD shall be consumed. For they shall be ashamed of the terebinth trees which you have desired; And you shall be embarrassed because of the gardens Which you have chosen. For you shall be as a terebinth whose leaf fades, And as a garden that has no water. The strong shall be as tinder, And the work of it as a spark; Both will burn together, And no one shall quench them.
