'Keep All My Commandments' in the Bible

Oh that there were such a heart in them, that they would fear me, and keep all my commandments always, that it might be well with them, and with their children for ever!

Concerning this house which thou art building, if thou wilt walk in my statutes, and execute mine ordinances, and keep all my commandments to walk in them; then will I establish my word with thee, which I spake unto David thy father.
