Can you provide any kind of source material for this...all the resources I have simply translate the word as dance.
When a translation is made, many translators even today, still doesn't know the meaning of certain words.
So, how the actual meaning is derived? It is based on context and the use in other places. However, you can ask any Bible scholar for the meanings of words that occurs only once or twice with no proper description, like the shape of Noah's boat (which is also used to describe the shape of the basket of Moses). But, no one really knows to best describe it to common people. Hence, the translator puts his own thoughts to describe with the best with what he can. No translator lived 3000 years back to fully understand the language and the word usage and all the ancient Hebrew/Greek languages are taught are based on the context/occurring in other places and also referring to other non-biblical sources for the use of that word.
There is also another way to cross verify. We have LXXE (Septuagint) translated from Hebrew into Greek around 300 BC. So, we have the translation with what the people understood the best in 2 languages atleast 2000 years back .
If you look into the usage of dancing esp. David, it is often related to joy not the same word used to describe the dance of Miriam. Hence, there are two words and these two words does not mean the same in original texts but English does not have those words to exactly represent it.
I believe you said, you don't dance. However, in Psalms and Proverbs, He will turn your mourning into 'dancing?'. You can still dance with sorrow (sorrow itself can dance as in Job 41:22). The actual word is 'joy' not dance because, in Jer 31:13 God turns mourning to joy, not dancing.
There must be two/three witness in the law and this is confirmed in NT as well as a witness. Christ Himself has two other witness who is His Father and the Spirit giving witness to Him. Similarly, if you have any doubt in any verse, there must be two to three witness of other verses confirming the other verse one from OT and another from NT. I can't find such witness for 'dancing' for it to be followed.
