From an early age, we have been taught to tell the truth. In his sefer S’fas Tamim, the Chofetz Chaim writes that falsehood is the only sin in the Torah where we are explicitly required to keep a distance from, as it says; “Keep away from anything false” (Sh’mos 23:7). When you think about it, it’s truly amazing. We know how serious sins are, especially idol worship, murder, kidnapping, and forbidden sexual relationships (among others). Yet the only time the Torah shows us that big yellow sign – “Caution: Stay away” – is when it comes to lying.
