Bekah in the Bible

And it cometh to pass when the camels have finished drinking, that the man taketh a golden ring (whose weight is a bekah), and two bracelets for her hands (whose weight is ten bekahs of gold),

A bekah for every man, that is, half a shekel, after the shekel of the sanctuary, for every one that went to be numbered, from twenty years old and upward, for six hundred thousand and three thousand and five hundred and fifty men.
