'Existed' in the Bible

He was not the Light, but he existed that he might give testimony concerning the Light.

And now, Father, do Thou glorify me in Thine own presence, with the glory that I had in Thy presence before the world existed.

For they are wilfully blind to the fact that there were heavens which existed of old, and an earth, the latter arising out of water and extending continuously through water, by the command of God;

I am writing to you, fathers, because you know Him who has existed from the very beginning. I am writing to you, young men, because you have overcome the Evil one. I have written to you, children, because you know the Father.

I have written to you, fathers, because you know Him who has existed from the very beginning. I have written to you, young men, because you are strong and God's Message still has a place in your hearts, and you have overcome the Evil one.

And the Wild Beast which once existed but does not now exist--he is an eighth king and yet is one of the seven and he goes his way into perdition.
