'True God' in the Bible

Now for a long while Israel was without the true God, and without a teaching priest, and without law;

And his servants spoke yet more against Jehovah, the true God, and against his servant Hezekiah.

And this is the eternal life, that they should know thee, the only true God, and Jesus Christ whom thou hast sent.

for they themselves relate concerning us what entering in we had to you, and how ye turned to God from idols to serve a living and true God,

And we know that the Son of God has come, and has given us an understanding that we should know him that is true; and we are in him that is true, in his Son Jesus Christ. He is the true God and eternal life.
