'Dynasty' in the Bible

The tribe of Benjamin, relatives of Saul numbered 3,000, of whom most had remained allied to what remained of Saul's dynasty.

"Because of you, my God, I have been bold to pray to you, as you have told your servant that you will build him a dynasty.

Furthermore, it has pleased you to bless the dynasty of your servant, so that it will continue in place forever in your presence, because when you, LORD, grant a blessing, it is an eternal blessing."
