Ish-bosheth, Saul's son, was forty years old when he began to reign over Israel, and he reigned two years. But the house of Judah followed David.

Isboseth the son of Saul was forty years old when he began to reign over, Israel, and he reigned two years: and only the house of Juda followed David.

Ishbosheth Saul's son was forty years old when he began to reign over Israel, and he reigned two years. However, the house of Judah followed David.

(Ish-bosheth Saul's son was forty years old when he began to reign over Israel, and he reigned two years.) But the house of Judah followed David.

A son of forty years, is Ish-Bosheth son of Saul, in his reigning over Israel, and two years he hath reigned, only the house of Judah have been after David.

(Saul's son Ish-bosheth was forty years old when he became king over Israel, and he was ruler for two years.) But Judah was on the side of David.

Ishbosheth, the son of Saul, was forty years old when he had begun to rule over Israel. And he reigned for two years. For only the house of Judah followed David.

Forty two - The numerals are somewhat strange. First, as regards the 40 years. Even assuming that Ish-bosheth's reign did not commence until five and a half years after Saul's death, which must have been the case if the two years in the text gives the true length of his reign, it is startling to hear of Saul's younger son being 35 years old at his father's death, born consequently some three years before his father's accession, and five years older than David, the bosom friend of his older brother Jonathan. The age, too, of Jonathan's child, Mephibosheth, who was five years old at his father's death, would lead one to expect rather a less age for his uncle. Next, as regards the two years. Since David (compare 2-Samuel 2:11; and marginal references) reigned seven years in Hebron over Judah only, it follows, if the two years in the text are correct, either that an interval of five years elapsed between Ish-bosheth's death and David's being anointed "king over all Israel," or that a like interval elapsed between Saul's death and the commencement of Ish-bosheth's reign. Of the two the latter is the more probable, and has the advantage of diminishing Ish-bosheth's age by between five and six years. But the narrative in 2 Sam. 3; 2-Samuel 4:1-12 of the "long war," of the birth of David's six sons, and of Abner's conspiracy and death, seems to imply a longer time than two years, in which case both the numerals would have to be corrected.

Ish-bosheth - reigned two years - It is well observed that Ish-bosheth reigned all the time that David reigned in Hebron, which was seven years and six months. Perhaps the meaning of the writer is this: Ish-bosheth reigned two years before any but the tribe of Judah had attached themselves to the interest of David. Some think that Abner in effect reigned the last five years of Ish-bosheth, who had only the name of king after the first two years. Or the text may be understood thus: When Ish-bosheth had reigned two years over Israel, he was forty years of age. Houbigant, dissatisfied with all the common modes of solution, proposes to read ששית שנה shishshith shanah, six years, for the שתים שנים shetayim shanim, two years, of the text, which he contends is a solecism; for in pure Hebrew the words would be שתים שנה as they are everywhere read in the first book; and שנה is the reading of eleven of Kennicott's MSS., and nine of De Rossi's; but the number two is acknowledged by all the ancient versions, and by all the MSS. yet collated. The critical reader may examine Houbigant on the place. After all, probably the expedition mentioned in the succeeding verses is that to which the writer refers, and from which he dates. Ish-bosheth had reigned two years without any rupture with David or his men, till under the direction of Abner, captain of his host, the Israelites passed over Jordan, from Mahanaim to Gibeon, and being opposed by Joab, captain of David's host, that battle took place which is described in the following verses.

Ishbosheth, Saul's son, was forty years old when he began to reign over Israel,.... Being born the same year his father began to reign. See Gill on 1-Samuel 31:6,
and reigned two years; which some understand of these, and no more; and whereas David reigned seven years and a half over Judah, before he reigned over all Israel, it is thought by the Jewish chronologer (c) that there was a vacancy in the throne of Israel for the space of five years, and so says Kimchi; which vacancy was either before the reign of Ishbosheth, it being a matter in dispute whether he or Mephibosheth should be set up, or after his death; the tribes of Israel being so long before they acknowledged David their king; or Ishbosheth's reign of two years must be in the middle of David's reign over Judah; but there is no need to suppose either of these, for the text says not that Ishbosheth reigned only two years; but the meaning is, as Ben Gersom observes, that he had reigned two years when the following things happened, and a war began, and not by him but by Abner, and carried on by him; and he being an inactive prince, the rest of his reign was reckoned as no reign, whereas he lived and reigned the same length of time David did over Judah; see 2-Samuel 3:1,
but the house of Judah followed David; kept close to him as their king, yielding a cheerful obedience to him.

Length of the reigns of Ishbosheth over Israel, and David at Hebron. The age of Ishbosheth is given, as is generally the case at the commencement of a reign. He was forty years old when he began to reign, and reigned two years; whereas David was king at Hebron over the house of Judah seven years and a half. We are struck with this difference in the length of the two reigns; and it cannot be explained, as Seb. Schmidt, Clericus, and others suppose, on the simple assumption that David reigned two years at Hebron over Judah, namely up to the time of the murder of Ishbosheth, and then five years and a half over Israel, namely up to the time of the conquest of Jerusalem: for this is at variance with the plain statement in the text, that "David was king in Hebron over the house of Judah seven years and a half." The opinion that the two years of Ishbosheth's reign are to be reckoned up to the time of the war with David, because Abner played the principal part during the other five years and a half that David continued to reign at Hebron, is equally untenable. We may see very clearly from 2 Samuel 3-5 not only that Ishbosheth was king to the time of his death, which took place after that of Abner, but also that after both these events David was anointed king over Israel in Hebron by all the tribes, and that he then went directly to attack Jerusalem, and after conquering the citadel of Zion, chose that city as his own capital. The short duration of Ishbosheth's reign can only be explained, therefore, on the supposition that he was not made king, as David was, immediately after the death of Saul, but after the recovery by Abner of the land which the Philistines had taken on this side the Jordan, which may have occupied five years.
(Note: From the fact that in 2-Samuel 2:10, 2-Samuel 2:11, Ishbosheth's ascending the throne is mentioned before that of David, and is also accompanied with a statement of his age, whereas the age of David is not given till 2-Samuel 5:4-5, when he became king over all Israel, Ewald draws the erroneous conclusion that the earlier (?) historian regarded Ishbosheth as the true king, and David as a pretender. But the very opposite of this is stated as distinctly as possible in 2-Samuel 2:4. (compared with 2-Samuel 2:8). The fact that Ishbosheth is mentioned before David in 2-Samuel 2:10 may be explained simply enough from the custom so constantly observed in the book of Genesis, of mentioning subordinate lines or subordinate persons first, and stating whatever seemed worth recording with regard to them, in order that the ground might be perfectly clear for relating the history of the principal characters without any interruption.)

Two years - Namely, before the following war broke out, which continued five years.
