'Charge' in the Bible

Another angel, who was in charge of the fire, came from the altar and called in a loud voice to the angel who had the sharp sickle, "Use your sharp sickle and gather the clusters of grapes off the vine of the earth, because its grapes are now ripe."

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.
