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.

Note A half shekel is approximately 0.2 ounces or 5.7 grams; also in verse 15.

Note 20 gerahs is equivalent to one shekel (approximately 0.4 ounces or 11.4 grams).

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.

They shall give this, everyone who passes over to those who are counted, half a shekel according to the shekel of the sanctuary (the shekel is twenty gerahs); half a shekel for an offering to the Lord.

Note A shekel is about 10 grams or about 0.35 ounces.

Note a gerah is about 0.5 grams or about 7.7 grains

This they shall give, every one that passeth over unto them that are numbered, half a shekel after the shekel of the sanctuary; (the shekel is twenty gerahs), half a shekel for an offering to Jehovah.
