'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 sons forever!

Concerning this house that thou are building, if thou will walk in my statutes, and execute my ordinances, and keep all my commandments to walk in them, then I will establish my word with thee, which I spoke to David thy father.
