'Saviour' in the Bible

This is what the Lord of armies has said: See, I will be the saviour of my people from the east country, and from the west country;

And the Lord their God will be their saviour in that day, giving them food like the flock of his people: for they will be like the jewels of a crown shining over his land.

And I will make the children of Judah strong, and I will be the saviour of the children of Joseph, and I will make them come back again, for I have had mercy on them: they will be as if I had not given them up: for I am the Lord their God and I will give them an answer.
