Yep, Strongs seems to agree. Murder does mean kill.
The meaning of Hebrew words is determined by context. That's the nature of the language. It was a spoken language before it was a written one, so it lacks the precision of a language like Greek. In fact, written
Hebrew doesn't even record the vowels, only the consonents. The way you tell the difference between words is through context. Between 700-1100 A.D., the
Masoretes developed vowel points to assist the readers of their day because they were not very familiar with the vast Hebrew lexicon and did not always know what the alternative possibilities for a set of Hebrew consonants might be.
While the word can mean "murder", the context determines whether it means "murder" or "kill". So you can't simply pull out a lexicon or the Strong's and proclaim the definitive meaning of a word out of its context. And the fact that the same word can be used for "murder" or "kill" does not mean that the meaning is the same.
