Isn't an "I'm sorry" good enough?
"Whosoever commits sin transgresses also the Torah: for sin is the transgression of the Torah."
1Jn 3:4
"there is joy in the presence of the angels of Elohiym over one sinner that repents."
Luk 15:10
“For if after they have escaped the pollutions of the world through the knowledge of The Master the Savior Yahusha Ha’Mashiach, they are again entangled therein, and overcome, the latter end is WORSE with them than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to TURN BACK FROM the set-apart commands delivered unto them. But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.”
2Pe 2:20-22
