'Conquered' in the Bible

I will grant the one who conquers permission to sit with me on my throne, just as I too conquered and sat down with my Father on his throne.

Then one of the elders said to me, "Stop weeping! Look, the Lion of the tribe of Judah, the root of David, has conquered; thus he can open the scroll and its seven seals."

Then I saw something like a sea of glass mixed with fire, and those who had conquered the beast and his image and the number of his name. They were standing by the sea of glass, holding harps given to them by God.
