Are there any instances in the Bible of God speaking to more than one person at a time?

In almost every instance I know of in the Bible where God speaks to someone, or an angel appears to someone, it is always a lone person. The exception I know of is Adam and Eve. When God spoke to Moses with the burning bush and later on the mountaintop, Moses was alone. No witnesses were there to confirm that Moses was not a liar or a lunatic. But I'm not a biblical scholar. Are there any instances in the Bible where God speaks to two or more people at once?
