What do they not say to their hearts?
Rashi: That all their evil is written in front of Me for a remembrance.
Radak: That I remember all their evil.
Malbim: When they suffered evils, they thought that I remember their evil and punish them. Therefore, their evil was not so revealed. When I wanted to heal them, and I widened their border, they do not say that I remember all their evil. They think that I forgot it and I will not punish. Therefore, they sin openly.
What is the meaning of "Atah Sevavum Ma'aleleihem Neged Panai Hayu"?
Radak: Now their evil deeds will surround them. They were in front of My face; they were not hidden from Me. When they will receive the punishment, they will recognize that I knew everything, and I return payment [for their deeds] on their heads.
Malbim: There is no need for Me to remember their previous evil ? now their current evil deeds are in front of My face!
