Isaiah 49: 8 - 15 is today's first reading.
In reading it,
Thus says the LORD: "In a time of favor I have answered you, in a day of salvation I have helped you; I have kept you and given you as a covenant to the people, to establish the land, to apportion the desolate heritages;
9 saying to the prisoners,
Come forth,' to those who are in darkness,Appear.' They shall feed along the ways, on all bare heights shall be their pasture;
Who is the "you" is it the prophet Isaiah or is it the people of Israel?
The answer to me is important in understanding:
"I have kept you and given you as a covenant to the people, to establish the land, to apportion the desolate heritages;"
My initial thought was it is to Isaiah but then could it be said that Isaiah as prophet is "a covenant" to Israel?
