'Ones' in the Bible

I said to him, “Sir, you know.”Then he told me:These are the ones coming out of the great tribulation.They washed their robes and made them whitein the blood of the Lamb.

These are the ones not defiled with women, for they have kept their virginity. These are the ones who follow the Lamb wherever He goes. They were redeemed from the human race as the firstfruits for God and the Lamb.
