Elijah went into heaven. Elisha saw it. Elisha cried out "My father, my father, the chariot of Israel, and the horsemen thereof." Elijah was taken up to heaven in a chariot of fire. Elisha saw him no more. Gabriel came to the Prophet Daniel and said at the beginnings of Daniel's supplications the commandment came forth to go to him. Revelation has a scripture that describes golden vials full of odours, which are the prayers of saints. Revelation has another scripture that describes the the prayers of all saints upon the altar which was before God's throne. Everyone of those are simply more desperate attempts that do not constitute prayer being made to created beings in Heaven. Elisha saying "My father, my father when Elijah was being taken up to heaven is not a prayer at all, but an simply exclamation that asks nothing.
Gabriel coming to the Prophet Daniel in response to his prayer to God is not that of praying to angels.
Angels and elders offering up prayers before the judgments of the last days in memorial (Rev. 5:8 and 8:3,4; f. Lv. 2:2,15,16; 24:7; Num. 5:15) is not even a continuous postal service, and does not constitute praying to them, or manifest the ability of created beings to hear all prayer from Heaven, which is unique to God
Give it up. It only makes you look worse.
Elisha saying "My father, my father when Elijah was being taken up to heaven is not a prayer at all, but an simply exclamation that asks nothing.
You left out the rest of what Elisha said. It is not
simply an exclamation that asks nothing, for it is repeated later in the same book. It is a cry for help from the designated deliverer of Israel when it appears that deliverer will be taken from Israel. King Joash uses the same cry to the Prophet Elisha as Elisha used with the Prophet Elijah, and then Elisha provides deliverance through the spirit of Elijah (which you correctly stated was the Spirit of God), according to the faith of King Joash. Elisha chastised King Joash for not having more faith by which his prayer would have been answered with more deliverance from the adversaries of Israel.
Now Elisha was fallen sick of his sickness whereof he died. And Joash the king of Israel came down unto him, and wept over his face, and said, O my father, my father, the chariot of Israel, and the horsemen thereof. And Elisha said unto him, Take bow and arrows. And he took unto him bow and arrows. And he said to the king of Israel, Put thine hand upon the bow. And he put his hand upon it: and Elisha put his hands upon the king's hands. And he said, Open the window eastward. And he opened it. Then Elisha said, Shoot. And he shot. And he said, The arrow of the LORD's deliverance, and the arrow of deliverance from Syria: for thou shalt smite the Syrians in Aphek, till thou have consumed them. And he said, Take the arrows. And he took them. And he said unto the king of Israel, Smite upon the ground. And he smote thrice, and stayed. And the man of God was wroth with him, and said, Thou shouldest have smitten five or six times; then hadst thou smitten Syria till thou hadst consumed it: whereas now thou shalt smite Syria but thrice.
