In 2 Kings 6 and 7 God gives Elisha the ability to hear his enemy’s plans while he is making them in private. When the Arameans army comes to attack Elisha prays that God will help his people see the army of angels that is protecting them. God blinds the the enemy army and Elisha leads them into Samaria. He had the people of Israel feed them . They did not attack Israel for some time.
Later the Arameans lay siege on Samaria starving the people until they resort to cannibalism. The king complains to Elisha and he tells the king that the next day they will have plenty. God confuses the Arameans and they leave their camp and all of their supplies. The people of Israel can eat.
In 2 Corinthians 4 Paul speaks of being faithful to present the gospel even though he is enduring much hardship. He knows that the glory should be given to God. If thing would go easily the temptation would be to take the credit. As it is God receives all the glory.
Paul is preparing to die knowing that this momentary affliction will lead to eternal glory.
