Therefore the flight shall perish from the swift, and the strong shall not strengthen his force, neither shall the mighty deliver himself:
Therefore the flight shall perish from the swift - even the swift shall not be able to escape. Or, "flight" may be put for "a place of flight" (Psalms 142:4-5; Job 11:20, margin).
And the strong shall not strengthen his force - i:e., shall not be able to use his strength.
Neither shall the mighty be able to deliver himself - literally, his life.
