Answer:
It is Latin for "Our Father", the Model Prayer: Matthew 6:9-13--"YOU must pray, then, this way:"'Our Father in the heavens, let your name be sanctified. Let your kingdom come. Let your will take place, as in heaven, also upon earth. Give us today our bread for this day; and forgive us our debts, as we also have forgiven our debtors. And do not bring us into temptation, but deliver us from the wicked one.' This was call 'the Model Prayer' because it is a outline for how to pray, not what words to use. First, we must give glory to God, using His name, (not Lord or God or any other 'titles' people use) Jehovah), praying for His will to take place. Then, each person has different needs, or 'daily bread' that they need to pray about. Afterwards, we ask for forgiveness for our sins, forgiveness if we have offended others, and forgiveness to those who have offended you. However, many people do not read: Matthew 6:7,8--'But when praying, do not say the same things over and over again, just as the people of the nations do, for they imagine they will get a hearing for their use of many words. So, do not make yourselves like them, for God YOUR Father knows what things YOU are needing before ever YOU ask him". There are many religions that repeat the same words over again, using 'rosary beads', and/or 'prayer wheels' (Buddist, Catholic, Hindu and many others). God wants sincere prayer, not 'often repeated' poetry.
This is an excellent, Bible based observation. I'm not sure about the )after the name Jehovah. It may be a typo of some kind. God's name, as revealed to his chosen people, at least at that time, Israel, was of course in Hebrew, not English. The Hebrew language is rather complicated and not as orderly as most languages today in that it only used consonants. Vowels were not used in print, but of course they were used in speaking. The vowels were inserted by the person speaking based on a number of things known about the word. The four consonants used to print in Hebrew the name of God was YHWH, which is generally pronounced as Yahweh, inserting the vowels a and e. Since few people speak Hebrew, or would want to (except perhaps Jews), it needed to be
transliterated into modern languages such as English. The Latin equivalent is JHVH, which leads to the most accepted pronunciation of the original Hebrew Text, or Jehovah, again inserting the vowels of e and o. But the Divine Name was held extremely sacred, as it should be of course. Over time, there seemed to be a reluctance to use the name and to write the name in scrolls out of fear of not pronouncing it correcting or inadvertently copying it wrong, despite the extreme care taken by scribes. In the Old Testament, the Divine Name is used thousands of times, based on the oldest original texts or copies, such as the Dead Sea Scrolls. Perhaps one of the 10 Commandments, "Do Not Take The Name Of The Lord In Vain" had something to do with the evolution of using the name, since the name itself is not used in the commandment, only Lord, which is not a name, but a title that is accorded to God the Almighty.
Of course as the centuries passed on, many religions were formed and many, many "Gods" were invented and worshipped by the various Gentile nations, while Israel held to the one true God, the Creator of Heaven & Earth, not imitation gods made of wood, metal or clay; gods that needed to be made by humans to have their existence, rather than the God who created all things.
The use of Jehovah in Christian times quickly diminished giving way to Jesus Christ, the Messiah & Deliverer of mankind sent to earth from God. Jesus then becomes the central figure of Christianity, and rightfully so as Jehovah primarily represents the time leading up to Christ, just as the Old Law Covenant was replaced with the New Covenant, which redeemed not only Jews but the entire human race from captivity to sin and death, if people exercised faith in the Redeemer, Jesus. Thus, Jesus becomes the focal point of the New Testament, representing his Father as a Son, but not just a little baby or child, as is often depicted by Christmas. He is the King of Kings, Lord of Lords. Powerfully, and valiantly He brings on the war of Armageddon to the Earth and Satan & his demon horde. He is the savior in every way possible. For those already dead throughout the centuries, he is the "resurrection & the life", for he then resurrects the dead as he did Lazarus as an example of his future powers and duties within his position as King of the Kingdom. (Messianic Kingom) As a result of this, and getting back to the original subject of The Lord's Prayer, this is the reason Jesus answers the question of how to pray. He does not actually use the Divine Name in his answer because he knows that the Jews, & soon the Gentiles, will need to get accustomed to placing their faith in him, and the name of Jesus must become the main theme for centuries and eternity to come. As such Jesus becomes the Lord God because he assumes all the duties & responsibilities assigned to him by his Father in order to extricate the hopeless human condition from its containment to sin and death, as well as perfectly displaying the personality of the Father. Thus, seeing and listening to Jesus, was in effect, the same as if they were seeing and listening to his Father. The two were in perfect unison.
However, these basic truths have been corrupted over the centuries by various forces meant to confuse the truth of God' purposes and deceive mankind.
