'Scale' in the Bible
If anyone is untrue, sinning in error in connection with the holy things of the Lord, let him take his offering to the Lord, a male sheep from the flock, without any mark, of the value fixed by you in silver by shekels, by the scale of the holy place.
then the priest shall look at the infection, and if it appears to be deeper than the skin and there is thin yellowish hair in it, then the priest shall pronounce him unclean; it is a scale, it is leprosy of the head or of the beard.
But if the priest looks at the infection of the scale, and indeed, it appears to be no deeper than the skin and there is no black hair in it, then the priest shall isolate the person with the scaly infection for seven days.
On the seventh day the priest shall look at the infection, and if the scale has not spread and no yellowish hair has grown in it, and the appearance of the scale is no deeper than the skin,
then he shall shave himself, but he shall not shave the scale; and the priest shall isolate the person with the scale seven more days.
Then on the seventh day the priest shall look at the scale, and if the scale has not spread in the skin and it appears to be no deeper than the skin, the priest shall pronounce him clean; and he shall wash his clothes and be clean.
But if the scale spreads farther in the skin after his cleansing,
and the priest examines it and finds the scale to have spread on the skin, the priest need not look for yellowish hair, since he is clean.
If in his sight the scale has remained, however, and black hair has grown in it, the scale has healed, he is clean; and the priest shall pronounce him clean.
This is the law for any mark of leprosy—even for a scale,
And let the years be numbered from the time when he gave himself to his owner till the year of Jubilee, and the price given for him will be in relation to the number of years, on the scale of the payment of a servant.
And you will put the value of a male from twenty years to sixty years old at fifty shekels of silver, by the scale of the holy place.
