'Beginning' in the Bible

And to the angel of the church in Laodicea write: These things saith the Amen, the faithful and true witness, the beginning of the creation of God:

And he said unto me, They are come to pass. I am the Alpha and the Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.

I am the Alpha and the Omega, the first and the last, the beginning and the end.
