Why Jesus wasn't given the proper name "Immanuel"?

[TonyChanYT]

Isaiah 7:

14 Therefore the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel.

So why Jesus wasn't given the proper name "Immanuel"?

Barnes explained:

We are not, then, to suppose that the child should actually receive the name Immanuel as a proper name, since, according to the usage of the prophet, and especially of Isaiah, that is often ascribed to a person or thing as a name which belongs to him in an eminent degree as an attribute;

Isaiah used the idiom "call him" to designate an attribute. He did it again in Isaiah 62:

4 No longer will they call you Deserted, or name your land Desolate. But you will be called Hephzibah, and your land Beulah; for the LORD will take delight in you, and your land will be married.

Matthew explained in 1:

21 She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” 22 All this took place to fulfill what the Lord had spoken by the prophet:
23 “Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel”
(which means, God with us). 24 When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, 25 but knew her not until she had given birth to a son. And he called his name Jesus.

"Call his name Immanuel" was an idiom for attributing "God with us" to Jesus.

Another similar case is found in Jeremiah 23:

5 “Behold, the days are coming, declares the LORD, when I will raise up for David a righteous Branch, and he shall reign as king and deal wisely, and shall execute justice and righteousness in the land. 6 In his days Judah will be saved, and Israel will dwell securely. And this is the name by which he will be called: ‘The LORD is our righteousness.’

In the OT and NT, "name" does not always refer to his literal personal name. The word "name" often refers to the person's title, reputation, character, or authority. Even today, sometimes we use it like that.

Understanding the words does not mean one understands the language.
When words are 'understood' one will argue about words and ask the most inane questions.

'Language' encompasses relationship .....something which is alien to words.
The language of relationship is recognised by those in relationship. To those who are not, all they can do is debate and make words (often plenty).....as the former is a mystery to them. (mystery, as in non accessible)
