Why use "Yahwev" instead of "God" or "Lord"

Exodus 20:7
-KJV: Thou shalt not take the name of the LORD (03068) thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain.
-ASV: Thou shalt not take the name of Jehovah thy God in vain; for Jehovah will not hold him guiltless that taketh his name in vain.

Strong's number 03068:
Jehovah = "the existing One"
the proper name of the one true God

Yahwev or Jehovah ?

In Exodus 20:7, we are told not to take His Name in vain. The word “vain” comes from the Hebrew shaw, meaning “worthlessness.”
When we ignore His Name we are breaking this commandment. Also, according to the Old and New testaments, those who call upon Yahweh’s Name will be saved, Joel 2:32 and Acts 2:21.
Beyond the scriptural significance, people prefer being called by their personal names and not by a replacement someone may randomly choose. Our Creator is no different.
He too desires to be called by His personal revealed Name, Yahweh.
