Tenth

We recently had to translate Isaiah 6 from Hebrew into English for our "Exegesis of Isaiah" class. The assignment was my first big translating effort since I took Hebrew last fall. In 6:13 we read about a tenth of the people returning to the land. The Hebrew word was literally translated "tenth." I haven't done much translation of the whole Old Testament (yet), but the "tenth" stuck out to me. The other place the Hebrews talked about a "tenth" was in their tithing system. Could there be any connection between the "tenth" of the people who would return to the land and the "tenth" that would be offered to the Lord?
