2 Samuel 3:1

There was long war. — Not actual fighting of pitched battles, but a state of hostility, in which Ish-bosheth and David each claimed the allegiance of the whole nation, and this continued until the death of Ish-bosheth. During this time Ish-bosheth was too weak to carry on actual war, and David was content to abide the fulfilment of the promises of the Lord in His own good time.

Waxed stronger. — Time was working in David’s favour, partly, doubtless, on account of Ish-bosheth’s manifest incompetence, partly from a growing appreciation of the character and prowess of David, and a fuller realisation that he was the divinely appointed sovereign. In 1 Chronicles 12:19 there is an account of an important accession to David from the tribe of Manasseh on the eve of Saul’s last battle, and a further mention of continued accessions to him “day by day.” As the necessary result of this constant transference of strength to David, “the house of Saul waxed weaker and weaker.”
