כדור Suddenly.5A. V., Round about. Comp. 22:18.6It is not clear what I. E. means by comparing this passage with 22:18. כדור in that verse means a ball, a round thing. It would be rather far-fetched to suppose that it meant here as quickly and as suddenly as a ball flying through the air meets us. See c. xxii., note 26.
Rashi
a camp of siege (מֻצַּב, lit. stationed,) an expression of a camp of siege stationed against the towns.
