Yeshua is the Word. He was there in the beginning and will be there in the end and forever more. The alpha and Omega (Aleph Tav) Heaven and Earth shall pass away, but His WORD never will. When Yeshua knelt down and wrote in the dirt then drew a line in the sand, He was telling the Pharisees he is the one who wrote the law (words) on the Tablets with His finger on the mountaintop and gave them to Moses. They knew this is what He was saying.

Revelation 1:8

I am Alpha and Omega, the beginning and the ending, says the Lord, which is, and which was, and which is to come, the Almighty.

Shabbat Shalom
