(5) Seven years and six months.--The six months is also mentioned in 2 Samuel 2:11; 1 Chronicles 3:4, but, as being only the fraction of a year, is generally omitted in the summary of the length of his reign, as in 2 Samuel 5:4; 1 Chronicles 29:27. It was the habit of the sacred historians either to omit such fractions or else to count them as whole years, thus introducing a certain element of indefiniteness into the chronology, which is very marked in the parallel narratives of the kings of Israel and of Judah.
5:1-5 David was anointed king a third time. His advances were gradual, that his faith might be tried, and that he might gain experience. Thus his kingdom typified that of the Messiah, which was to come to its height by degrees. Thus Jesus became our Brother, took upon him our nature, dwelt in it that he might become our Prince and Saviour: thus the humbled sinner takes encouragement from the endearing relation, applies for his salvation, submits to his authority, and craves his protection.
In Hebron he reigned over Judah seven years and six months,.... So long the kingdom of Israel continued in the house of Saul after his death; and by this it appears that David was near thirty eight years of age when the elders of Israel came and made him their king:
and in Jerusalem he reigned thirty and three years over all Israel and Judah; which in all made forty years and six months, see 1 Kings 2:11; upon his being made king over all the tribes, as soon as he had taken the strong hold of Zion, which he immediately attacked, as follows, he removed the seat of his kingdom from Hebron to Jerusalem.
