That's an interesting question. The difference in the canon examples is that -be' follows tu' when -jaj or -'a' is appended. I would expect the difference to be that tu'be'lu' means that someone unspecified does not observe (though someone else might), while tu'lu'be' would mean no one observes, but {yIH tu'be'lu'jaj} doesn't follow this pattern.

Is there any conclusion to be made from the Ca'Non examples posted? Because I don't see any difference regarding the when each variation is to be used.--
