'Someone' in the Bible

Cross over to Cyprus and take a look.Send someone to Kedar and consider carefully;see if there has ever been anything like this:

They are well-fed, eager stallions,each neighing after someone else’s wife.

for the customs of the peoples are worthless.Someone cuts down a tree from the forest;it is worked by the hands of a craftsman with a chisel.

All your lovers have forgotten you;they no longer look for you,for I have struck you as an enemy would,with the discipline of someone cruel,because of your enormous guiltand your innumerable sins.
