What is "Bato'ach Al Tohu"?
Radak: When Ploni speaks with his friend, it is Sheker - his heart is unlike his mouth. His friend trusts in nothingness, for Ploni thinks in his heart that his friend will not find out if he speaks falsely. It is revealed in front of Hashem! Also, one day Ploni's heart will be seen from his actions; his friend trusted in vain.
Malbim: There are two groups of deniers. One of them does not investigate at all. Their denial is not based on philosophical proofs. They speak Sheker based on trust in nothingness. There is no content in their words or the foundation on which they rely. Also refer to 59:4:4:2.
What is the meaning of "Haro Amal v'Holid Aven"?
Radak: The verse depicts intent as pregnancy, and speech and deed to birth [of sin].
