Yes. Absolutely.

At the following link is a description and pictures of one of the oldest surviving copies of the Ten Commandments (a Decalogue). It is etched onto the smooth side of a large rock and the language it is written in is ancient Hebrew.

It is called the Los Lunas Dacalogue Stone.

This Decalogue is located in some rock formations in New Mexico in the American southwest which is home to many Native American tribes.

The Los Lunas Decalogue Stone is thought to have been written by an ancient Hebrew people. Its origin dates back approx. 3,000 years ago.

The Los Lunas Decalogue Stone first became well known "to the World" in the 1850s. However, at that time the local people had already been well aware of it for a very long time.
