'Half shekel' in the Bible

And it happened [that] as the camels finished drinking the man took a gold ring of a half shekel in weight and two bracelets for her arms, ten shekels in weight,

This they will give, {everyone who is counted}, the half shekel, according to the sanctuary shekel, [which is] twenty gerahs per shekel. The half shekel [is] a contribution for Yahweh.

The rich will not give more, and the poor will not give less than the half shekel to give the contribution of Yahweh to make atonement for their lives.

[It was] a bekah for the individual, the half shekel according to the sanctuary shekel, for {everyone who was counted}, from {twenty years old} and above, for six hundred and three thousand five hundred and fifty.
