'Families' in the Bible

And the families of Judah will say in their hearts, The people of Jerusalem have their strength in the Lord of armies, their God.

In that day I will make the families of Judah like a pot with fire in it among trees, and like a flaming stick among cut grain; they will send destruction on all the peoples round about, on the right hand and on the left: and Jerusalem will be living again in the place which is hers, that is, in Jerusalem.

And all the other families by themselves, and their wives by themselves.

And it will be that if any one of all the families of the earth does not go up to Jerusalem to give worship to the King, the Lord of armies, on them there will be no rain.
