Leviticus 19:14 "Nor shall you put a stumbling block before the blind"

It is unlikely that a person would purposely cause a blind person to fall!

However, this Negative Mitzvah implies more than that.

Blindness means not being able to see, but it does not only apply to the loss of eyesight.

A person who does not know certain things may also be considered "blind" - "unknowing" in those matters.

When he asks us for information and advice, we should give him the right answer. If we misguide him, he may do wrong, suffer a loss, make a mistake or fail.

The Torah cautions us never to cause another person to suffer because of bad advice or instructions that we give them. We must be careful and try to guide the person correctly and properly.
