Others "upon" is not quite correct, especially for the early examples where the word (rare in Syriac!) tends to be used in place of simple ˁl where the reference is to the space above something. In any case, prior to the late Babylonian dialects, this form, as opposed to ˁl, is only used in reference to physical space, and exceptions in the prints should be considered to be scribal errors. The rare prepositional examples in Syriac seem always to carry the connotation of "protection".
