Exodus 12:43

“But the deceitful, and he that is not pure of heart, and possesses nothing that is pure (as the Proverb saith, ‘To a deceitful man there is nothing good’), shall assuredly, being a stranger, and of a different race from the saints, be accounted unworthy to eat the Passover, for ‘a foreigner shall not eat of it.’” — editor's note: Exod. xii. 43.

“…as indeed we learn from the historical account, ‘A man who is of another nation, or bought with money, or uncircumcised, shall not eat the Passover.’” — editor's note: Ib. xii. 43–48.
