To be שמר שבת means to keep, or guard, Sabbath.
“Shamar (some are) calling me a guard! But I am a corrections officer!”

I am a Mom and Grandma who began studying Hebrew to assist my understanding of the Hebrew praise songs I was singing for our Messianic Jewish Synagogue praise team way back in 2001. A home educator at the time, this quickly led to learning Hebrew in order to teach my children.
