'Families' in the Bible

You are the sons of the prophets, and of the agreement which God made with your fathers, saying to Abraham, Through your seed a blessing will come on all the families of the earth.

And he made with him the agreement of which circumcision was the sign. And so Abraham had a son, Isaac, and gave him circumcision on the eighth day; and Isaac had a son, Jacob, and Jacob was the father of the twelve heads of the families of Israel.

So it is my desire that the younger widows may be married and have children, controlling their families, and giving the Evil One no chance to say anything against them,

By whom some families have been completely overturned; who take money for teaching things which are not right; these will have to be stopped.
