'Hands' in the Bible

After these things I looked, and this is what I saw: a vast multitude which no one could count, [gathered] from every nation and from all the tribes and peoples and languages [of the earth], standing before the throne and before the Lamb (Christ), dressed in white robes, with palm branches in their hands;

The rest of mankind, who were not killed by these plagues, did not repent even then of the works of their hands, so as to cease worshiping and paying homage to the demons and the idols of gold and of silver and of bronze and of stone and of wood, which can neither see nor hear nor walk;

Also he compels all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead [signifying allegiance to the beast],

Then I saw something like a sea or large expanse of glass mixed with fire, and those who were victorious over the beast and over his image and over the number corresponding to his name were standing on the sea or large expanse of glass, holding harps of God [worshiping Him].

And then I saw thrones, and sitting on them were those to whom judgment [that is, the authority to act as judges] was given. And I saw the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had refused to worship the beast or his image, and had not accepted his mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years.
