What does Adeste opportune mihi vorago mean?

Answer:
"Be conveniently present for me, chasm." It's hard to know how to interpret this, because adeste ("be present") is plural. If the chasm is being addressed, it should be the singular ades instead. On the other hand, if I'm calling myself a chasm, then vorago should be voragini (dative) to agree with mihi.
