What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it.

Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

His mother saith unto the servants, Whatsoever he saith unto you, do it.

Ye are my friends, if ye do whatsoever I command you.

And we have confidence in the Lord touching you, that ye both do and will do the things which we command you.
