Who may not testify?
Many are pasul only mid'Rabbanan
Those who chase money can be bribed
Some paid witnesses to lie about the moon
Dice players
Restrictivethe ones who are unfit:
Taking another's money — or: no honest work (Rambam)
Lenders at interest
Pigeon-racers
Or: those who lure others' birds
Traders in Shemittah produce
And slaves
The rule: where a woman may not testify, neither may they
General ruleThis is the general rule:
A woman may testify that a husband died
Restrictivethey too are not fit for it.
Rosh Hashana 1:8

וַעֲבָדִים.

אַף הֵן אֵינָן כְּשֵׁרִים לָהּ:
