The Sabbath in Different Languages
The Sabbath is not just a Hebrew word.
In fact the word Sabbath still exists in many other languages today (at least 80, but some say 105+).
I suspect that at the time of the tower of Babel the word Sabbath was well known as the seventh day (a day of rest). When God confounded the languages a remnant of that word must have made it into all other languages, which explains why they are still so similar today.
Here are some really cool articles about this.
I think this is absolutely awesome, because it proves that all languages have a common ancestor, and also confirms that the seventh day Sabbath is a day of rest.
Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
