Mark 1:3 Prepare the way of the Lord

Mark 1:3
”the voice of one crying in the wilderness. Prepare the way of the Lord (κυριου kyriou), make His paths straight." (LITV)

The name YHWH is translated into words kyrios (κυριος) in the LXX (Septuagint) and because of the LXX became a reference point for the writers and the early Christian church, so kyrios words in the books of the New Testament, so many which are intended to declare the name of YHWH. From the example in Mark 1:3 mentioned above, can be compared that Mark was referring to the books of the Septuagint translation of Isaiah 40:3 because the exact same sentence structure. While the Septuagint kyriou is a translation of the name YHWH in the Old Testament texts in Hebrew. From this it will be easy to conclude that the author of the Gospel of Mark since the first paragraph of his book have informed his readers that John the Baptist (because of this verse speaks of John the Baptist) has prepared the way for kyriou (that is YHWH) and in this case is Jesus (which is incarnation of the Word of YHWH himself).
If we want to see again in the text of the Septuagint, in Isaiah 43:10 (LITV) YHWH said, "that you may know (Greek: γνωτε gnote) and believe (πιστευσητε pisteusēte) Me, and understand that I am He (εγω ειμι ego eimi). ", as a form of Self declaration of YHWH to his people and we align with Self declarations of Jesus as follows:" Therefore, I said to you that you will die in your sins. For if you do not believe (πιστευσητε pisteusēte) that I AM (εγω ειμι ego eimi), you will die in your sins. "(John 8:24, LITV), and" When you lift up the Son of Man, then you will know (γνωσεσθε gnōsesthe) that I AM (εγω ειμι ego eimi); "(John 8:28, LITV). We can easily see the parallel of 3 words from YHWH Self declaration with Self declaration of Jesus in the Gospel of John: gnosesthe, pisteusete and ego eimi. John took the same attitude with Mark that Jesus equates HimSelf with YHWH (because He is the incarnation of the Word of YHWH HimSelf).
