King James Version
Let destruction come upon him at unawares; and let his net that he hath hid catch himself: into that very destruction let him fall.English Standard Version
Let destruction come upon him when he does not know it! And let the net that he hid ensnare him; let him fall into it--to his destruction!New International Version
may ruin overtake them by surprise- may the net they hid entangle them, may they fall into the pit, to their ruin.
