lick the dust - in abject prostration as suppliants (Psa 72:9; compare Isa 49:23; Isa 65:25).
move out of their holes - As reptiles from their holes, they shall come forth from their hiding-places, or fortresses (Psa 18:45), to give themselves up to the conquerors. More literally, “they shall tremble from,” that is, tremblingly come forth from their coverts.
