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),

[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.
