Is there a possibility of being kind to an angel or are we just entertaining for angels to watch?

Question:

In Hebrews 13:2 it says we are to be hospitable because in doing so some have entertained angels unawares. I'm trying to understand if this means there is a possibility we could show kindness to an actual angel (appearing as a human), or if by "entertaining" it is talking about them being entertained (i.e. rejoicing) by what we do to real humans during our lifetime.

Answer:

"Do not forget to entertain strangers, for by so doing some have unwittingly entertained angels" (Hebrews 13:2).

The command to entertain strangers is given support by noting that some in the past have entertained angels without being aware of who their guests were. For example, Abraham served a meal for angels (Genesis 18). Lot took two angels into his home (Genesis 19). It isn't that everyone has entertained angels or that this is a common occurrence. The point is that no one ever knows when they might be entertaining an angel, so being hospitable should not be neglected.
