All angels have limited knowledge and function.
Three ‘men’ came to Abraham and told him he would have offspring by Sarah. That was one function, so in Gen 19:1 there were two ‘men’; one to save Lot’s family and one to destroy Sodom.
They said “we have come to destroy” so I tended to think of their mission as a rescue and a destroy two person “team” sort of deal. (I sometimes wonder if it was Moses and Elijah and Jesus that visited Abraham....it could be since where God is concerned, time is fluid; persons and angels on God’s sort of missions could be going backwards and forwards in time.We all read of Elijah and Moses and Jesus talking to one another at the mount of Transfiguration where Christ is revealed in his true full glory and so were Elijah and Moses. Even if the “two men” weren’t M and E but angels, the story is compelling.)
