'Free' in the Bible

and from Jesus Christ -- the faithful witness, the firstborn from among the dead, the ruler over the kings of the earth. To the one who loves us and has set us free from our sins at the cost of his own blood

Then the kings of the earth, the very important people, the generals, the rich, the powerful, and everyone, slave and free, hid themselves in the caves and among the rocks of the mountains.

saying to the sixth angel, the one holding the trumpet, "Set free the four angels who are bound at the great river Euphrates!"

Then the four angels who had been prepared for this hour, day, month, and year were set free to kill a third of humanity.

He also caused everyone (small and great, rich and poor, free and slave) to obtain a mark on their right hand or on their forehead.

to eat your fill of the flesh of kings, the flesh of generals, the flesh of powerful people, the flesh of horses and those who ride them, and the flesh of all people, both free and slave, and small and great!"

He also said to me, "It is done! I am the Alpha and the Omega, the beginning and the end. To the one who is thirsty I will give water free of charge from the spring of the water of life.

And the Spirit and the bride say, "Come!" And let the one who hears say: "Come!" And let the one who is thirsty come; let the one who wants it take the water of life free of charge.
