'Set' 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

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.
