'My People' in the Bible

“Many nations will join themselves to the Lord on that day and become My people. I will dwell among you, and you will know that the Lord of Hosts has sent Me to you.

The Lord of Hosts says this: “I will save My people from the land of the east and the land of the west.

I will bring them back to live in Jerusalem. They will be My people, and I will be their faithful and righteous God.”

I will put this third through the fire;I will refine them as silver is refinedand test them as gold is tested.They will call on My name,and I will answer them.I will say: They are My people,and they will say: Yahweh is our God.”
