'My People' in the Bible

And he went and sent to Jehoshaphat the king of Judah, saying, The king of Moab has rebelled against me: will you go with me against Moab to battle? And he said, I will go up: I am as you are, my people as your people, and my horses as your horses.

Turn again, and tell Hezekiah the ruler of my people, Thus says the LORD, the God of David your father, I have heard your prayer, I have seen your tears: behold, I will heal you: on the third day you shall go up unto the house of the LORD.
