'Strongholds' in the Bible

I will indeed bless you, and I will greatly multiply your descendants so that they will be as countless as the stars in the sky or the grains of sand on the seashore. Your descendants will take possession of the strongholds of their enemies.

They blessed Rebekah with these words: "Our sister, may you become the mother of thousands of ten thousands! May your descendants possess the strongholds of their enemies."
