'First fruits' in the Bible

But, in truth, Christ has been raised from the dead, the first-fruits of those who are at rest.

But each in his proper order-Christ the first-fruits; afterwards, at his Coming, those who belong to the Christ.

I have another request to make of you, Brothers. You remember Stephanas and his household, and that they were the first-fruits gathered in from Greece, and set themselves to serve Christ's People.

These are the men who never defiled themselves in their intercourse with women; they are as pure as virgins. These are the men who follow the Lamb wherever he goes. They were redeemed as the first-fruits of mankind for God and for the Lamb.
