I should really call this my word language key. For those who are unfamiliar with some of the terms that I use like Yah and YHWH. I wanted to provide a quick summary:
יהוה=YHWH=LORD, and can be pronounced in various ways such as Yahweh, Yahuwah, Yahuah, Jevovah, Yehovah.
His name is made up of three Hebrew letters: Yod Hey Vav. His Name YHWH(or YHVH) spells out Yod Hey Vav Hey, and an amazing part about this is what it means, as each Hebrew word represents something:
•Yod stands for Hand / Arm
•Hey stands for Look! / Behold! / to Reveal!
•Vav stands for Nail / Hook / Secure
Thus his name YHWH means: Hand Behold Nail Behold (reading from L to R)
In the NT, you will mostly see the usage of Lord, like Lord Jesus. This refers back to the usage of LORD, however things got lost in translation. Here is a great breakdown of the usage of Lord in the NT, and an amazing correlation to LORD in the OT: https://biblicalgreeknuggets.blogspot.com/2011/03/yahweh-adonai.html
Also the use of Yah(or Jah), is just a short version of Yahweh, and in some passages within the KJV were preserved.
I also generally use the Name Yeshua for the Name of our Saviour, but of course also recognize Jesus, as well as other versions of His Name in other languages. If interested in a quick breakdown here is a short example, and may lead you to look into more:
