In the religious sphere, Jehovah is one of the names by which God is known, indeed, it is one of the most used in the Old Testament. As is known, the Old Testament was written in Old Hebrew, which at that time did not use vowels. Therefore, the name of God was written with 4 consonants "YHVH".
YHVH's name is found written in Latin lines as "Yahveh" "Yahweh" which when translated means "He who will be, is and was". The Jews felt immense respect for the name of God, that is why they did not pronounce it, abiding by what is written in the third commandment: "You shall not use God's name in vain." The Jews to refer to God used other names such as Adonay which means our Lord; Emmanuel "HE Lord among us or" Elohim "God of gods.
Experts in the field consider that the correct pronunciation is Yahweh and that the term Jehovah originated by introducing the vowels AOA of the word Adonay, in the name YHVH. Whenever the name of YHVH appeared in some texts, the vowels of “Adonay” were immediately added to it, in this way it served as a reminder for people to pronounce the name Jehovah instead of the sacred name.
In the sacred texts you can find other compound names such as Jehovah Jireh, which means "the Lord my provider"; Jehovah Nissi "the lord is my flag" or Jehovah Tsidkenu "Lord of justice", with all these compounds the different qualities of God himself are revealed.
En resumen, la palabra de Jehová significa “El gran Yo soy”, englobando de esta manera los demás nombres de Dios. Dando muestra de que Él es el creador y Señor de todo lo existente y que sin Él no hay nada.
