This they shall give, every one that passeth among them that are numbered, half a shekel after the shekel of the sanctuary: (a shekel [is] twenty gerahs:) an half shekel [shall be] the offering of the LORD.
Berean Study Bible (BSB) - Exodus 30:13 >Everyone who crosses over to those counted must pay a half shekel, according to the sanctuary shekel, which weighs twenty gerahs. This half shekel is an offering to the LORD.
