re: "I don't see the name Jehovah in the bible"

Recall that Jesus taught his followers to pray: “Our Father in the heavens, let your name be sanctified.” We can have a part in sanctifying God’s name by making it known. Doing so draws us closer to him.—Matthew 6:9

“I am Jehovah. That is my name.”—Isaiah 42:8

Jehovah promises: “I will protect him because he knows my name. He will call on me, and I will answer him. I will be with him in distress.” (Psalm 91:14, 15) Knowing and using Jehovah’s name does matter if we wish to enjoy a close relationship with him.

Psalm 83:18

May people know that you, whose name is Jehovah, You alone are the Most High over all the earth.

Psalm 83:18 stating Jehovah (as God's name) is recorded in many old Bible's no matter the version/how old it may be etc.
