Jehoshaphat ascended the throne in the fourth year of Ahab 1Ki 22:41, probably after that monarch had contracted his alliance with the royal family of Sidon, and before he was engaged in war with Syria. It was thus not unnatural that Jehoshaphat should begin his reign by strengthening himself against a possible attack on the part of his northern neighbor.
The first ways of his father David - The Septuagint and several Hebrew manuscripts omit “David,” which has probably crept in from the margin, for David’s “first ways” are nowhere else contrasted with his later ways. The real meaning of the writer is, that Jehoshaphat followed the example set by his father Asa in his earlier years 2Ch 14:1-15; 15.
Baalim - On the plural form, see 1Ki 18:18 note.
The doings of Israel - i. e. the especially idolatrous doings of the time - the introduction and establishment of the worship of Baal and the groves.
Presents - i. e. “free-will offerings,” in addition to the regular taxes. See 1Sa 10:27.
His heart was lifted up - This expression generally occurs in a bad sense Deu 8:14; 2Ch 26:16; Psa 131:1; Pro 18:12; but here it must be taken differently. The margin “was encouraged” expresses fairly the true meaning. He first began by setting an example of faithfulness to Yahweh. He then proceeded to use his best endeavors to extirpate idolatry.
He took away the high places - Compare 2Ch 20:33, and see the 2Ch 15:17 note.
The princes were not sent as teachers themselves, but had the duty committed to them of seeing that the people were taught. The actual teachers were the priests and Levites of 2Ch 17:8.
There is no reasonable doubt that this “book of the law” was the Pentateuch - nearly, if not quite, in the shape in which we now have it. Copies of the whole Law were, no doubt, scarce; and therefore Jehoshaphat’s commission took care to carry a copy with them.
Some of the Philistines brought Jehoshaphat presents - i. e. “some of the Philistines were among his tributaries.” Compare 2Sa 8:2; 1Ki 4:21.
Tribute silver - Or, “much silver” - literally “silver of burthen.”
The Arabians - The Arab tribes who bordered Judaea to the south and the southeast paid Jehoshaphat a fixed tribute in kind. Compare 2Ki 3:4 note.
The captains of thousands; Adnah the chief - literally, “princes of thousands, Adnah the prince.” The writer does not mean that Adnah (or Johohanan, 2Ch 17:15) was in any way superior to the other “princes,” but only that he was one of them.
Three hundred thousand - This number. and those which follow in 2Ch 17:15-18, have been with good reason regarded as corrupt by most critics. For:
(1) They imply a minimum population of 1,480 to the square mile, which is more than three times greater than that of any country in the known world (circa 1880’s).
(2) they produce a total just double that of the next largest estimate of the military force of Judah, the 580, 000 of 2Ch 14:8.
(3) they are professedly a statement, not of the whole military force, but of the force maintained at Jerusalem (2Ch 17:13; compare 2Ch 17:19).
It is probable that the original numbers have been lost, and that the loss was suppplied by a scribe, who took 2Ch 14:8 as his basis.
