What does that have ANYTHING to do with the Bible listing two angels, and then another part of it listing one angel at the tomb? Or one section saying a person is 22, and another 42? It seems when things don't go as you plan, you take the "God is sovereign" defense. This comes from your literalist view of Scripture, trying to see God writing Scriptures in a manner that "Allah" wrote the Koran. Christianity is not Islam or Judaism. It is not a religion of the Book, but a religion about a Man - Jesus Christ.
I've been away and I have lost track of the run of this conversation. But reviewing my answer I believe I was answering Kosta response that he didn't read the Bible but trust God. My answer has nothing to do with your question. However if you must know it was Jewish custom to only refer to the main person who was doing the talking and ignore the second. Consequently in Matthew's account, which was written to a Jewish audience, he properly and quite frequently mentions only one person (or angel) where in the other accounts mentions two. It is not erroreous but simply a style of writing practiced in that day.
