2 Samuel 3:2 In-Context

1 Therefore a long strife was made betwixt the house of David and the house of Saul; and David profited and ever[more] was stronger than himself, in comparison of time passed, for his power increased ever, but the house of Saul decreased each day. (And so for a long time there was strife between the house of David and the house of Saul; and David grew in strength, that is, as more time that passed, the more his power increased, but the house of Saul grew ever weaker.)
