'Trapping' in the Bible

Therefore trapping nets [are] all around you, and panic suddenly terrifies you,

Dread, and pit, and a trapping net [are] against you, O inhabitant of Moab," {declares} Yahweh.

"He [who] flees {before} the dread will fall into the pit, and the [one who] climbs up from the pit will be caught in the trapping net, for I will bring on Moab the year of their punishment," {declares} Yahweh.

Does a bird fall into a trapping net on the earth when there is no snare for it? Does a trapping net spring up from the ground unless it has certainly caught something?
