Isaiah 50 – The significance of …has opened My ear ; … the Greek word Telos. It's earth shattering!

Isa 50:4 The Lord GOD has given Me the tongue of disciples, That I may know how to sustain the weary one with a word. He awakens Me morning by morning, He awakens My ear to listen as a disciple.
Now that Elohim stated that He can save Israel and Judah, He tells them of His Servant that He will use to do so. Yeshua was given the tongue of disciples, or taught ones, or the learned.
Luke 4:22 And all were speaking well of Him, and wondering at the gracious words which were falling from His lips; and they were saying, “Is this not Joseph’s son?”
Luke 4:31-32 And He came down to Capernaum, a city of Galilee. And He was teaching them on the Sabbath; 32and they were amazed at His teaching, for His message was with authority.
John 7:46 The officers answered, “Never did a man speak the way this man speaks.”
Isa 50:5 The Lord GOD has opened My ear; And I was not disobedient, Nor did I turn back.
Elohim had His ear opened. He was the faithful servant of Elohim who wished to stay with His Master because He loves His Master and the family given to Him.
Ex 21:5-6 “But if the slave plainly says, ‘I love my master, my wife and my children; I will not go out as a free man,’ 6then his master shall bring him to God, then he shall bring him to the door or the doorpost. And his master shall pierce his ear with an awl; and he shall serve him permanently.
This was also spoken of in
Psalm 40:6-8 Sacrifice and meal offering Thou hast not desired; My ears Thou hast opened; Burnt offering and sin offering Thou hast not required. 7Then I said, “Behold, I come; In the scroll of the book it is written of me; 8I delight to do Thy will, O my God; Thy Law is within my heart.”
