9 And he said, "Yes, go, and say to this people, 'Listen carefully, but do not understand. Watch closely, but learn nothing.' 10 Harden the hearts of these people. Plug their ears and shut their eyes. That way, they will not see with their eyes, nor hear with their ears, nor understand with their hearts and turn to me for healing." 11 Then I said, "Lord, how long will this go on?" And he replied, "Until their towns are empty, their houses are deserted, and the whole country is a wasteland; 12 until the Lord has sent everyone away, and the entire land of Israel lies deserted. 13 If even a tenth-a remnant-survive, it will be invaded again and burned. But as a terebinth or oak tree leaves a stump when it is cut down, so Israel's stump will be a holy seed."

Commentary on Isaiah 6:9-13
(Read Isaiah 6:9-13)
God sends Isaiah to foretell the ruin of his people. Many hear the sound of God's word, but do not feel the power of it. God sometimes, in righteous judgment, gives men up to blindness of mind, because they will not receive the truth in the love of it. But no humble inquirer after Christ, need to fear this awful doom, which is a spiritual judgment on those who will still hold fast their sins. Let every one pray for the enlightening of the Holy Spirit, that he may perceive how precious are the Divine mercies, by which alone we are secured against this dreadful danger. Yet the Lord would preserve a remnant, like the tenth, holy to him. And blessed be God, he still preserves his church; however professors or visible churches may be lopped off as unfruitful, the holy seed will shoot forth, from whom all the numerous branches of righteousness shall arise.
