Looking at the reference there, I am reminded of Genesis 2:19, 20
19 Now Jehovah God had been forming from the ground every wild animal of the field and every flying creature of the heavens, and he began bringing them to the man to see what he would call each one; and whatever the man would call each living creature, that became its name.
20 So the man named all the domestic animals and the flying creatures of the heavens and every wild animal of the field. . .
The name of each animal did identify their distinct characteristics. Like dog, cat, bird, etc, but those were not personal names, such as we give to our pets, like "Blackie", "Bob", "Whiskers", etc.
Likewise, man and woman are names identifying our characteristics, but they are not personal names.
River, is the name given to a body of water flowing from a source, but the "personal" name of the river sets it apart from others.
For example...
(Genesis 2:10-14)
10 Now there was a river flowing out of Eʹden to water the garden, and from there it divided into four rivers.
11 The name of the first is Piʹshon; it is the one encircling the entire land of Havʹi·lah, where there is gold.
12 The gold of that land is good. Bdellium gum and onyx stone are also there.
13 The name of the second river is Giʹhon; it is the one encircling the entire land of Cush.
14 The name of the third river is Hidʹde·kel; it is the one going to the east of As·syrʹi·a. And the
fourth river is the Eu·phraʹtes.
While there are infact many names for an individual, which are actually titles - man, business man, manager, architect, father, husband, etc. That individual has only one personal name.
Similarly, while God has many titles, which people prefer to refer to as names - God, Lord, Lord God, God Almighty, God, Supreme One, etc, God has only one personal name, which he alone has, and which he says people will have to know, whether they like it or not.
(Jeremiah 16:21) . . .“So I will make them know, At this time I will make them know my power and my might, And they will have to know that my name is Jehovah
יְהוָֹה Yhvh : the proper name of the God of Israel.”
Some people prefer to use the four constants JHWH, JHVH, YHWH, YHVH.
Some prefer the Hebrew translation / transliteration Yahweh.
Some prefer the commonly used English name Jehovah.
However, repeatedly, God has made his name known throughout his word, the Bible.
(Psalm 83:18) . . .May people know that you, whose name is Jehovah, You alone are the Most High over all the earth.
(Exodus 6:3) And I used to appear to Abraham, Isaac, and Jacob as God Almighty, but with regard to my name Jehovah I did not make myself known to them.
(Isaiah 42:8) I am Jehovah. That is my name; I give my glory to no one else, Nor my praise to graven images.
Does God have a personal name? Yes he does.
What is God's personal name? God tells us. "I am Jehovah
יְהוָֹה. That is my name..." (Isaiah 42:8)
God introduces himself to us, by name.
