The seal of the Holy one

--> God is righteous; be ye also righteous. Righteousness means love of truth, hatred of lying and backbiting. The seal of the Holy one, blessed be He, is Truth, of which actions of man should also bear the impress. Hence let thy yea be yea and thy nay, nay. He who is honest in money transactions, unto him this is reckoned  as if he had fulfilled the whole of the Torah.
