They analyze the possibility of multiple voices in the book and interpret phrases suggesting abandonment and lacking focus on God. The importance of looking back at God's actions in the past is emphasized. They also delve into the themes of greed, leadership, and God's discipline through the metaphor of pruning an olive tree.
Isaiah's vision highlights his overwhelming sense of unworthiness and the need for purification before serving God.

Isaiah's vision of the Lord and his response
Isaiah has a vision of the Lord seated on the throne with seraphim praising him. He feels overwhelmed by his own unworthiness and the sinful state of his people. An angel purifies Isaiah's lips with a hot coal and declares his guilt is taken away. Isaiah then hears the Lord asking for a messenger, and despite his fear, he volunteers and says, 'Send me.'
The importance of pruning and the remnant
Isaiah describes a vision of an olive tree being pruned, symbolizing God's discipline and purification of his people. However, Isaiah questions God about the extent of the destruction and negotiates for a smaller calamity. God responds that the punishment will be severe until only a remnant remains. The holy seed will be like a stump that grows into a restored and renewed people.
The call to prophetic duty and the consequences
Isaiah hears the voice of the Lord asking, 'Whom shall I send?' and he responds, 'Here am I, send me.' God then commissions Isaiah to go and deliver a message to the people. However, the message is one of hardening hearts and shutting their eyes, as they have become unresponsive to God's voice. This will result in their continued unbelief and lack of understanding, leading to destruction and exile.
