Our pursuers are on our necks,
We are weary, and have no rest.
The ‘pursuers' are probably the men set to watch over them as they went about their working day, or as they followed other pursuits. These ‘pursuers' were seemingly relentless in ensuring that they did not slacken off. Instead of them being ‘on our necks' we would say that they were ‘on our backs' (get off my back). And the relentless pressure was proving too much. They were very weary and were finding no opportunity to rest. (see Deuteronomy 28:43).
