עד היום הזה, even though you have witnessed all His great deeds.

אתם נצבים היום כולכם, as we know from verse 1:'ויקרא משה את כל ישראל וגו

למען ספות הרוה, the deliberate sinner, whose motivation is that seeing he is so well off, he does not worry about possible consequences for himself

הצמאה, because of the urgings of his desire. He does not sin in order to make a statement against G’d asserting his freedom to do as he pleases and thereby rejecting G’d as the world’s Master. He is merely unable to resist his urges.

כי בשרירות לבי, only because of assertion of self, of ego.

כי אז יעשן, G’d is not willing to forgive such a person, but considering his attitude, His anger will “smoke.”

על אשר עזבו, because, contrary to previous occasions, G’d’s anger could not be tempered by the consideration that the gentiles would consider G’d’s killing His people as proof that He was unable to keep His promise to the. I already explained on Deut. 9,28 that after the people had crossed the river Jordan such excuses could not longer be cited in their defense.

הנסתרות לה' אלוקינו, I have already explained this on Deut. 27,15 in connection with the curses pronounced at Mount Gerizim and Mount Eyval. It is precisely because sins committed in secret cannot be dealt with by the courts, that the Torah has to go on record that the sinner will still not get away with his sin.

לנו ולבנינו עד עולם, it is up to us to administer the penalties prescribed by the Torah subject to the offender being convicted on the basis of reliable witnesses.
