Paul contradicts God’s words in Exodus 20:1-2 on who gave the Law to Moses. Moses says it was Yahweh, and Paul says it was angels, not god, and uses that as proof why Galatians should not obey it.
Paul in Galatians says the Law given Moses was given by angels to Moses as a mediator, and not by God. If we want to go back to following the Law, Paul says we are desiring to submit to those who "are no gods." We want to submit to the "weak and beggarly elements (angels)." (Gal. 3:19; 4:8-9.) Thus, Paul clearly says the Law was not given by God.

1 Kings 13:4-6
Young Man of God Further Proves A True Prophet:
4 When the king heard the saying of the man of God, …His hand…he put out against him, dried up, so that he could not draw it back again to himself. 5 The altar was also split apart, ….6 The king answered the man of God, “Now intercede for the favor of Yahweh your God, and pray for me, that my hand may be restored me again.”
The man of God interceded with Yahweh, and the king’s hand was restored to him again, and became as it was before.

Young Prophet Followed Direct Revelation from Yahweh: No Lunch!
7 The king said to the man of God, “Come home with me and refresh yourself, and I will give you a reward.”
8 The man of God said to the king, “Even if you gave me half of your house, I would not go in with you, neither would I eat bread nor drink water in this place; 9 for so was it commanded me by Yahweh’s word, saying, ‘You shall eat no bread, drink no water, and don’t return by the way that you came.’ ” 10 So he went another way, and didn’t return by the way that he came to Bethel.

Old Prophet Seeks Out Young Prophet
11 Now an old prophet lived in Bethel, and one of his sons came and told him all the works that the man of God had done that day in Bethel. They also told their father the words which he had spoken to the king.
12 Their father said to them, “Which way did he go?” Now his sons had seen which way the man of God went, who came from Judah. 13 He said to his sons, “Saddle the donkey for me.” So they saddled the donkey for him; and he rode on it. 14 He went after the man of God, and found him sitting under an oak. He said to him, “Are you the man of God who came from Judah?”
He said, “I am.”

1 Kings 13:15-18
Old Prophet Contradicts Yahweh by purported ‘Angel’ message
15 Then he said to him, “Come home with me and eat bread.”
16 He [young prophet] said, “I may not return with you, nor go in with you. I will not eat bread or drink water with you in this place. 17 For it was said to me by Yahweh’s word, ‘You shall eat no bread or drink water there, and don’t turn again to go by the way that you came.’ ”
18 He said to him, “I also am a prophet as you are; and an angel spoke to me by Yahweh’s word, saying, ‘Bring him back with you into your house, that he may eat bread and drink water.’ ” He lied to him.2

1 Kings 13:19-22
So he went back with him, ate bread in his house, and drank water. 20 As they sat at the table, Yahweh’s word came to the prophet who brought him back; 21 and he cried out to the man of God who came from Judah, saying, “Yahweh says, ‘Because you have been disobedient to Yahweh’s word, and have not kept the commandment which Yahweh your God commanded you, 22 but came back, and have eaten bread and drank water in the place of which he said to you, “Eat no bread, and drink no water,” your body will not come to the tomb of your fathers.’

Yahweh’s True Word To Old Prophet Fulfilled
23 After he had eaten bread and after he drank, he saddled the donkey for the prophet whom he had brought back. 24 When he had gone, a lion met him by the way and killed him.

He came to the city of the old prophet to mourn, and to bury him. 30 He laid his body in his own grave; and they mourned over him, saying, “Alas, my brother!”
