Appearances of Angels to Men

Moses

Exodus 3:2  

There the angel of the LORD appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up.

Joshua

Exodus 23:20-23  

20 “See, I am sending an angel ahead of you to guard you along the way and to bring you to the place I have prepared.

21 Pay attention to him and listen to what he says. Do not rebel against him; he will not forgive your rebellion, since my Name is in him.

22 If you listen carefully to what he says and do all that I say, I will be an enemy to your enemies and will oppose those who oppose you.

23 My angel will go ahead of you and bring you into the land of the Amorites, Hittites, Perizzites, Canaanites, Hivites and Jebusites, and I will wipe them out.

Elisha and servant

2 Kings 6:16-17 

16 “Don't be afraid,” the prophet answered. “Those who are with us are more than those who are with them.”

17 And Elisha prayed, “O LORD, open his eyes so he may see.” Then the LORD opened the servant's eyes, and he looked and saw the hills full of horses and chariots of fire all around

Matthew 28:1-5  

1 After the Sabbath, at dawn on the first day of the week, Mary Magdalene and the other Mary went to look at the tomb.

2 There was a violent earthquake, for an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it.

3 His appearance was like lightning, and his clothes were white as snow.

4 The guards were so afraid of him that they shook and became like dead men.

5 The angel said to the women, “Do not be afraid, for I know that you are looking for Jesus, who was crucified.
