1) Elijah asks Elisha for any last requests: "When they had crossed over, Elijah said to Elisha, 'Ask what I shall do for you before I am taken from you.' And Elisha said, 'Please, let a double portion of your spirit be upon me.' He said, 'You have asked a hard thing. Nevertheless, if you see me when I am taken from you, it shall be so for you; but if not, it shall not be so.' As they were going along and talking, behold, there appeared a chariot of fire and horses of fire which separated the two of them. And Elijah went up by a whirlwind to heaven. Elisha saw it and cried out, 'My father, my father, the chariots of Israel and its horsemen!' And he saw Elijah no more. Then he took hold of his own clothes and tore them in two pieces. He also took up the mantle of Elijah that fell from him and returned and stood by the bank of the Jordan. He took the mantle of Elijah that fell from him and struck the waters and said, 'Where is the LORD, the God of Elijah?' And when he also had struck the waters, they were divided here and there; and Elisha crossed over. Now when the sons of the prophets who were at Jericho opposite him saw him, they said, 'The spirit of Elijah rests on Elisha.' And they came to meet him and bowed themselves to the ground before him." (2nd Kings 2:9-15)
2) Elisah asks the Lord to open the eyes of his servant, Gehazi: "Now the heart of the king of Aram was enraged over this thing; and he called his servants and said to them, 'Will you tell me which of us is for the king of Israel?' One of his servants said, 'No, my lord, O king; but Elisha, the prophet who is in Israel, tells the king of Israel the words that you speak in your bedroom.' So he said, 'Go and see where he is, that I may send and take him.' And it was told him, saying, 'Behold, he is in Dothan.' He sent horses and chariots and a great army there, and they came by night and surrounded the city. Now when the attendant of the man of God had risen early and gone out, behold, an army with horses and chariots was circling the city. And his servant said to him, 'Alas, my master! What shall we do?' So he answered, 'Do not fear, for those who are with us are more than those who are with them.' Then Elisha prayed and said, 'O LORD, I pray, open his eyes that he may see.' And the LORD opened the servant's eyes and he saw; and behold, the mountain was full of horses and chariots of fire all around Elisha." (2nd Kings 6:11-17)
3) Moses sees a portion of God's glory: "Then Moses said, 'I pray You, show me Your glory!' And He said, 'I Myself will make all My goodness pass before you, and will proclaim the name of the LORD before you; and I will be gracious to whom I will be gracious, and will show compassion on whom I will show compassion.' But He said, 'You cannot see My face, for no man can see Me and live!' Then the LORD said, 'Behold, there is a place by Me, and you shall stand there on the rock; and it will come about, while My glory is passing by, that I will put you in the cleft of the rock and cover you with My hand until I have passed by. Then I will take My hand away and you shall see My back, but My face shall not be seen.'" (Exodus 33:18-23)
4) God confronts Job: "Then the LORD said to Job, 'Will the faultfinder contend with the Almighty? Let him who reproves God answer it.' Then Job answered the LORD and said, 'Behold, I am insignificant; what can I reply to You? I lay my hand on my mouth. Once I have spoken, and I will not answer; Even twice, and I will add nothing more.' Then the LORD answered Job out of the storm and said, 'Now gird up your loins like a man; I will ask you, and you instruct Me. Will you really annul My judgment? Will you condemn Me that you may be justified?'" (Job 40:1-8)
5) Paul sees Heaven: "Boasting is necessary, though it is not profitable; but I will go on to visions and revelations of the Lord. I know a man in Christ who fourteen years ago--whether in the body I do not know, or out of the body I do not know, God knows--such a man was caught up to the third heaven. And I know how such a man--whether in the body or apart from the body I do not know, God knows-- was caught up into Paradise and heard inexpressible words, which a man is not permitted to speak. On behalf of such a man I will boast; but on my own behalf I will not boast, except in regard to my weaknesses. For if I do wish to boast I will not be foolish, for I will be speaking the truth; but I refrain from this, so that no one will credit me with more than he sees in me or hears from me. Because of the surpassing greatness of the revelations, for this reason, to keep me from exalting myself, there was given me a thorn in the flesh, a messenger of Satan to torment me--to keep me from exalting myself! Concerning this I implored the Lord three times that it might leave me. And He has said to me, 'My grace is sufficient for you, for power is perfected in weakness.'" (2nd Corinthians 12:1-9)
6) John sees Jesus: "When I saw Him, I fell at His feet like a dead man. And He placed His right hand on me, saying, 'Do not be afraid; I am the first and the last, and the living One; and I was dead, and behold, I am alive forevermore, and I have the keys of death and of Hades.'" (Revelation 1:17-18)
