'Souls' in the Bible

This is what the Lord has said: Take your place looking out on the ways; make search for the old roads, saying, Where is the good way? and go in it that you may have rest for your souls. But they said, We will not go in it.

So they will come with songs on the high places, flowing together to the good things of the Lord, to the grain and the wine and the oil, to the young ones of the flock and of the herd: their souls will be like a watered garden, and they will have no more sorrow.
