There are other commands, but one more is found in the last words of Matthew’s gospel: Matthew 28:19 Go, and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all things that I commanded you. Behold, I am with you always, even to the end of the age.” Amen.

I updated this by adding a couple of items that I had forgotten, and by rewording, on August 25, 2012. See also a post on Jesus and the Ten Commandments.
