'Overcame' in the Bible

To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.

And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.

I saw something like a sea of glass mixed with fire, and those who overcame the beast, his image, and the number of his name, standing on the sea of glass, having harps of God.
