'Double' in the Bible

When they came to Capernaum, those who collected the double-drachma tax approached Peter and said, “Doesn’t your Teacher pay the double-drachma tax?”

I planned with this confidence to come to you first, so you could have a double benefit,

Pay her back the way she also paid,and double it according to her works.In the cup in which she mixed,mix a double portion for her.
