When they arrived at Capernaum, those who were in charge of collecting the half-shekel Temple tax came to Peter and asked him, “Your teacher does pay the half-shekel tax, doesn't he?”
Each one who crosses over to those counted must give a half shekel (using the sanctuary shekel standard, which weighs twenty gerahs). This half shekel is an offering to the Lord.
This represents a beka per person, or half a shekel (using the sanctuary shekel standard) from everyone twenty years of age or older who had been censused, a total of 603,550 men.
