Hbr 13:2 Be not forgetful to entertain strangers: for thereby some have entertained angels unawares.
Genesis 18:
18 Now the Lord appeared to him by the oaks of Mamre, while he was sitting at the tent door in the heat of the day.
2 When he lifted up his eyes and looked, behold, three men were standing opposite him; and when he saw
them, he ran from the tent door to meet them and bowed himself to the earth,
3 and said, ]My Lord, if now I have found favor in Your sight, please do not pass Your servant by.
4 Please let a little water be brought and wash your feet, and rest yourselves under the tree;
5 and I will bring a piece of bread, that you may refresh yourselves; after that you may go on, since you have visited your servant. And they said, So do, as you have said.
6 So Abraham hurried into the tent to Sarah, and said, ]Quickly, prepare three measures of fine flour, knead
it and make bread cakes. 7 Abraham also ran to the herd, and took a tender and choice calf and gave
it to the servant, and he hurried to prepare it.
8 He took curds and milk and the calf which he had prepared, and placed it before them; and he was standing by them under the tree as they ate.
Angels in heaven eat food:
Psalm 78: 23 Though he had commanded the clouds from above, and opened the doors of heaven,
24 And had rained down manna upon them to eat, and had given them of the corn of heaven.
25 Man did eat angels' food: he sent them meat to the full.
Angels appear as men when they wish:
Tobit - Chapter 1 - Bible - Catholic Online - Chapter 5
1 Tobias then replied to his father Tobit, 'Father, I shall do everything you have told me.
2 But how am I to recover the silver from him? He does not know me, nor I him. What token am I to give him for him to believe me and hand the silver over to me? And besides, I do not know what roads to take for this journey into Media.'
3 Then
Tobit answered his son Tobias, 'Each of us set his signature to a note which I cut in two, so that each could keep half of it. I took one piece, and put the other with the silver. To think it was twenty years ago I left this silver in his keeping! And now, my child, find a trustworthy travelling companion-- we shall pay him for his time until you arrive back-- and then go and collect the silver from Gabael.'
4 Tobias went out to look for a
man who knew the way to go with him to Media. Outside he found
Raphael the
angel standing facing him, though he did not guess he was an
angel of God.
5 He said, 'Where do you come from, friend?' The
angel replied, 'I am one of your brother Israelites; I have come to these parts to look for work.'
Tobias asked, 'Do you know the road to Media?'
6 The other replied, 'Certainly I do, I have been there many times; I have
knowledge and experience of all the ways. I have often been to Media and stayed with Gabael one of our kinsmen who lives at Rhages in Media. It usually takes two full days to get from Ecbatana to Rhages; Rhages lies in the mountains, and Ecbatana is in the middle of the plain.'
7 Tobias said, 'Wait for me, friend, while I go and tell my father; I need you to come with me; I shall pay you for your time.'
8 The other replied, 'Good, I shall wait; but do not be long.'
9 Tobias went in and told his father that he had found one of their brother Israelites. And the father said, 'Fetch him in; I want to find out about his
family and tribe. I must see if he is going to be a reliable companion for you, my child.' So
Tobias went out and called him,'Friend,' he said,'my father wants you,'
10 The
angel came into the house;
Tobit greeted him, and the other answered, wishing him
happiness in plenty.
Tobit replied, 'Can I ever be happy again? I am a blind man; I no longer see the light of heaven; I am sunk in darkness like the dead who see the light no more. I am a man buried alive; I hear people speak but cannot see them.' The angel said,' Take comfort; before long God will heal you. Take comfort.' Tobit said, 'My son Tobias wishes to go to Media. Will you join him as his guide? Brother, I will pay you.' He replied,' I am willing to go with him; I know all the ways; I have often been to Media, I have crossed all its plains and mountains, and I know all its roads.'
