'Souls' in the Bible

And when he opened the fifth seal, I saw under the altar the souls of those who had been slaughtered because of the word of God and because of the testimony which they had,

And I saw thrones, and they sat down on them, and authority to judge was granted to them. And [I saw] the souls of those who had been beheaded because of the testimony about Jesus and because of the word of God, and who had not worshiped the beast or his image, and did not receive the mark on their forehead and on their hand, and they came to life and reigned with Christ [for] a thousand years.
