'Contribution' in the Bible

This is what everyone who is registered is to give: half a shekel according to the shekel of the sanctuary (the shekel weighs 20 gerahs), half a shekel as a contribution to the LORD.

All who are registered, 20 years of age and older, are to give a contribution to the LORD.

The rich person is not to give more, nor is the poor person to give less than the half shekel, when you give a contribution to the LORD to make atonement for yourselves.

Everyone who could give an offering of silver and bronze brought it as a contribution for the LORD. Also all who had acacia wood for any use in the work brought it.
