Kena Upanisad: Who is not possible to see with our eyes, but who, has endowed us with eyes to see, He, we know, is God. He alone is the one we worship, none else.Who we cannot hear through our ears, but who has given us the faculty of hearing, Hewe know is God. He alone is the One we worship, none else. Who never breathes, but who has endowed us with the breath of life, He,we know, is God. He alone is the One we worship, none else.
Reference to God- Bagravitam (Bhagavad Gita):Those who worship the demigods will take birth among the demigods, those who worship ghosts and spirits will take birth among such beings and those who worship Me will live with Me. If one offers Me with love and devotion a leaf, a flower, a fruit, or water, I will accept it.(Bhag9;25-26)
Also:Whatever a man may sacrifice to other Gods, O Son of Kunti, is really meant for Me alone, but is offered without true understanding.(Bhagrivat 9;23)
O Son of Kunti, all that you do, all that you eat, all that you offerand give away, as well as all austerities that you may perform, should be done as an offering to Me. (Bhag9-27)
Both of these books are older than the New Testament, and likely older than the Christian old testament. The original language is Sanskrit which definitely does predate the Jewish language. The Hindus who read these believe in One God called on by different names. These are part of the Hindu scriptures--in fact they are the most commonly read scriptures.
Bhagavad-Gita 4 " O Bharata! Whenever dharma(virtue) declines and sin arises I incarnate myself in visable form."
