Variantly: It is not written "asuf ('join') upon them evils," but "asfah ('end') upon them evils" — all of the punishments will end, but they (Israel) will not end. And thus is it written (Ibid.) "My arrows achaleh ('I will end') in them." It is not written "My arrows 'yichlu' ('will end') them, but "My arrows I will end in them" — My arrows will end, but they (Israel) will not end.
Variantly: "My arrows achaleh in them" — these are arrows of famine, as it is written (Ezekiel 5:16) "when I send the evil arrows of famine against them."
