'My People' in the Bible

In the past, when Saul was king, it was you who went at the head of Israel when they went out or came in; and the Lord your God said to you, You are to be the keeper of my people Israel, and their ruler.

In all the places where I have gone with all Israel, did I ever say to any of the judges of Israel, whom I made the keepers of my people, Why have you not made for me a house of cedar?

So now, say to my servant David, The Lord of armies says, I took you from the fields, from keeping sheep, so that you might be a ruler over my people Israel;

And I will make a resting-place for my people Israel, planting them there, so that they may be in the place which is theirs and never again be moved; and never again will they be made waste by evil men, as they were at first,

From the time when I put judges over my people Israel; and I will overcome all those who are against you; and I will make you great and the head of a line of kings.

Then David the king got up and said, Give ear to me, my brothers and my people; it was my desire to put up a house, a resting-place for the ark of the Lord's agreement, and for the foot-rest of our God; and I had got material ready for the building of it.

But who am I and what is my people, that we have power to give so freely in this way? for all things come from you, and what we have given you is yours.
