'Families' in the Bible

For see, I will send for all the families of the kingdoms of the north, says the Lord; and they will come, everyone placing his high seat at the way into Jerusalem, and against its walls on every side, and against all the towns of Judah.

Give ear to the words of the Lord, O sons of Jacob and all the families of Israel:

Let your wrath be let loose on the nations which have no knowledge of you, and on the families who give no worship to your name: for they have made a meal of Jacob, truly they have made a meal of him and put an end to him and made his fields a waste.

See, I will send and take all the families of the north, says the Lord, and Nebuchadrezzar, king of Babylon, my servant, and make them come against this land, and against its people, and against all these nations on every side; and I will give them up to complete destruction, and make them a cause of fear and surprise and a waste place for ever.

At that time, says the Lord, I will be the God of all the families of Israel, and they will be my people.

Have you taken note of what these people have said, The two families, which the Lord took for himself, he has given up? This they say, looking down on my people as being, in their eyes, no longer a nation.
