What arguments from scripture are given by Baptists for the belief that one third of the angels were banished from heaven with Satan?

I remember being taught in an Independent Fundamentalist Baptist Church when I was in middle school that Satan took one third of the angels in heaven with him after being cast out of God's presence for rebellion. The only biblical reference I can locate that might be construed as support for this belief is **Revelation 12:4**: >Its tail swept a third of the stars out of the sky and flung them to the earth. The dragon stood in front of the woman who was about to give birth, so that it might devour her child the moment he was born. (NIV) I'm sure there are other scriptures that are commonly used in conjunction with this one to justify the belief, but I can't find any that seem to make sense in context, or that address the topic specifically. After discussing this and other issues regarding angels with conservative Baptist friends of mine, I found that some of them base a significant portion of their beliefs about angels, the nephilim, and other supernatural activity and beings on the Book of Enoch, but they always emphasized that they do not view Enoch as canon and as having much less authority than the scriptures. How do Baptists who hold this position defend it using canonical scripture? Also, are there any significant denominations or popular preachers who have maintained this belief?
