2 Samuel 3:1

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.)

2 Samuel 3:1 Meaning and Commentary

2 Samuel 3:1

Now there was a long war between the house of Saul and the
house of David
The recent battle, though so much in favour of David, did not, put an end to the war between him and Ishbosheth, which lasted five years longer; for it was when Ishbosheth had reigned two years that that battle was fought, and he reigned five years longer; for not till his death, and when David had reigned above seven years in Hebron, was he made king over all Israel; and during this time peace was not made, but the war carried on; though perhaps not in pitched battles, of which we no more read, but in skirmishes:

but David waxed stronger and stronger;
he having the advantage in all such skirmishes, and persons continually coming over to his side from the several tribes:

and the house of Saul waxed weaker and weaker:
being always worsted whenever they skirmished with David's men, and by continual revolts from them. This is reckoned an emblem of the kingdoms of Christ and antichrist, the one increasing more and more, as it has and will do, and the other decreasing, and before long will be consumed; and of the two parties in a regenerate man, grace and indwelling sin, the one as to its exercise growing stronger and stronger, and the other as to its influence on the outward conversation weaker and weaker.

2 Samuel 3:1 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.)

2 And sons were born to David in Hebron; and his first begotten son was Amnon, of Ahinoam of Jezreel;

4 and the fourth was Adonijah, the son of Haggith; and the fifth was Shephatiah, the son of Abital;
