Proverbs 6:21

19 a false witness who gives false testimony, and one who stirs up discord among brothers.

20 My son, keep your father’s commandment, and do not forsake your mother’s teaching.

Bind them always upon your heart; tie them around your neck.

22 When you walk, they will guide you; when you lie down, they will watch over you; when you awake, they will speak to you.

23 For this commandment is a lamp, this teaching is a light, and the reproofs of discipline are the way to life,

Do read the surrounding verses too, because the context often says more than a single verse.
