As you hold by the five precepts, this is part of the protection that the Buddha provides: not only telling you that there is such a thing as skillful and unskillful action, but also telling you which actions are skillful, which actions are not.

"If you’re consistent in holding to the precepts, you’re providing safety to everybody. They don’t have to fear anything from you. They don’t have to fear that they’re going to be killed or that their things will be stolen by you or that you’ll engage in illicit sex with them or with the people they love. You’re not going to lie to them; you’re not going take intoxicants and behave in ways that are going to be harmful to them. You’re providing safety for them and, as he said, when you’re providing safety in a universal way like this, you’re going to have a portion of that safety yourself. If you can avoid unskillful actions, it’s like a hand that has no wound. You can pick up poison, and the poison doesn’t seep into the blood. If there is a wound, you’re not safe.

So as you hold by the five precepts, you can rejoice in the fact that you’re behaving in a safe way, and this is part of the protection that the Buddha provides: not only telling you that there is such a thing as skillful and unskillful action, but also telling you which actions are skillful, which actions are not."
