In the Hebrew tradition, the name of God was the holiest of all names and could not be used in vain. The respect for this commandment was so great, that the name would not be uttered altogether, replacing God’s name Jehova with words like Adonai (Lord) or HaShem (The Name). Even today Jewish will say HaShem (The Name) in place of God. Or they will write it as G-d in English, avoiding spelling out the complete word God.
Such is respect and obedience to one of the ten Mosaic commandments. The name was treated almost as the physical embodiment of God Himself…
So imagine an environment of such reverence towards God’s name when Jesus walked the earth or soon after His departure when the good news of Jesus was preached. The divine and saving name of Jesus was looked at as powerful as Jesus Himself. It would be only natural for people to understand this concept at that culture this way. So uttering the name of Yeshua the King was like invoking His very presence. You can imagine it was never used lightly or in vain! It’s like having obtained the direct phone number of the Prime Minister, you would only call it when you had something worthwhile and important to say, not any time you had an urge to say something…
The Hebrew word for “name” - Shem - comes from the same root as “breath”. When you call out someone by his or her name, you use your breath, it’s breathing out that person’s essence. As Hebrews looked at breath as what contains life in you. It wasn’t gas exchange due to lungs, diaphragm and muscles working by the lower brain automatic function. No, the air in you moving in and out was The Living Spark of God in you which allowed you to be a living soul!
So it was a super huge deal to breath out a name!!! It’s akin to an act of creation by you… Powerful powerful stuff
