Would they able to obey?

How did the Israelites hear in the time of Exodus when God commanded them,

“You shall not do what is done in the land of Egypt where you lived

(for around 400 years from Jacob and his sons),

nor are you to do what is done in the land of Canaan where I am bringing you;

you shall not walk in their statutes”? (Lev. 18:3)

Although God clearly commanded them

“you do not practice any of the abominable customs which have been practiced before you” (v. 30),

Did the Israelites really obey this command of God?

Although God commanded them,

“You are to perform My judgments and keep My statutes” (v. 4),

Did the Israelites obey that command?
