'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 so the land will mourn, families by families, alone by themselves the family of the house of David by itself with their wives by themselves, the family of the house of Nathan by itself with their wives by themselves,

All the families that remain, every family apart, and their wives apart.

And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.
