And thou shalt write upon them all the words of this law, when thou art passed over; that thou mayest go in unto the land which the LORD thy God giveth thee, a land flowing with milk and honey, as the LORD, the God of thy fathers, hath promised thee.

And the Levites shall speak, and say unto all the men of Israel with a loud voice:

And the Levites shall speak, and say unto all the men of Israel with a loud voice:

Cursed be he that maketh the blind to go astray in the way. And all the people shall say: Amen.

משגה עור [CURSED BE] HE THAT CAUSES THE BLIND TO GO ASTRAY — This means: one who is blind (inexperienced) in a matter and one gives him bad advice (cf. Rashi on Leviticus 19:14).

ולפני עור לא תתן מכשל THOU SHALT NOT PUT A STUMBLING BLOCK BEFORE THE BLIND — This implies: "Give not a person who is "blind" in a matter an advice which is improper for him. Do not say to him: "Sell your field and buy from the proceeds of the sale an ass", the fact being that you are endeavouring to circumvent him and to take it (the field) from him (Sifra, Kedoshim, Section 2 14).

Cursed be he that taketh a bribe to slay an innocent person. And all the people shall say: Amen.
