And it came to pass after this, that Absalom prepared him chariots and horses, and fifty men to run before him.

Now after these things Absalom made himself chariots, and horsemen, and fifty men to run before him.

And it came to pass after this, that Absalom prepared for himself chariots and horses, and fifty men to run before him.

And it cometh to pass afterwards, that Absalom prepareth for himself a chariot, and horses, and fifty men are running before him;

Now after this, Absalom got for himself a carriage and horses, and fifty runners to go before him.

And after this Absalom began to furnish himself with a chariot and horses, and fifty men to run before him.

Then, after these things, Absalom obtained for himself chariots, and horsemen, and fifty men who went before him.

And it came to pass - The working out of Nathan's prophecy (marginal reference) is the clue to the course of the narrative. How long after Absalom's return these events occurred we are not told.

Absalom prepared him chariots and horses - After all that has been said to prove that horses here mean horsemen, I think it most likely that the writer would have us to understand chariots drawn by horses; not by mules or such like cattle.
Fifty men to run before him - Affecting in every respect the regal state by this establishment. Of this man Calmet collects the following character: "He was a bold, violent, revengeful, haughty, enterprising, magnificent, eloquent, and popular prince; he was also rich, ambitious, and vain of his personal accomplishments: after the death of Amnon, and his reconciliation to his father, he saw no hindrance in his way to the throne. He despised Solomon because of the meanness of his birth, and his tender years. He was himself of the blood royal, not only by his father David, but also by his mother Maacah, daughter to Talmai, king of Geshur: and, doubtless, in his own apprehension, of sufficient age, authority, and wisdom, to sustain the weight of government. There was properly now no competitor in his way: Amnon, David's first-born, was dead. Of Chileab, his second son by Abigail, we hear nothing; and Absalom was the third: see 2-Samuel 3:2-5. He, therefore, seemed to stand nearest to the throne; but his sin was, that he sought it during his father's life, and endeavored to dethrone him in order to sit in his stead.

And it came to pass after this, that Absalom prepared him chariots and horses, and fifty men to (a) run before him.
(a) Which were as a guard to set forth his estate.

And it came to pass after this,.... After the reconciliation of David and Absalom, and the latter was admitted to court again:
that Absalom prepared him chariots and horses; to make himself look grand and respectable among the people; perhaps he got these from his grandfather at Geshur in Syria:
and fifty men to run before him; which added to his pomp and magnificence; and such great personages in later time have had; Nero the Roman emperor never went on a journey with less than a thousand calashes or chariots, and a great number of men that ran before him (c): and this was tacitly setting himself up for king, at least preparing for it, as Adonijah afterwards did in the same way and manner, 1-Kings 1:5.
(c) Suetonius in Vit. Neron. c. 30. Vid. Senecae, Ep. 87. & 123.

David allows Absalom's pomp. Those parents know not what they do, who indulge a proud humour in their children: many young people are ruined by pride. And those commonly are most eager for authority who least understand its duties.

ABSALOM STEALS THE HEARTS OF ISRAEL. (2-Samuel 15:1-9)
Absalom prepared him chariots and horses, and fifty men to run before him--This was assuming the state and equipage of a prince. The royal guards, called runners, avant couriers, amounted to fifty (1-Kings 1:5). The chariot, as the Hebrew indicates, was of a magnificent style; and the horses, a novelty among the Hebrew people, only introduced in that age as an appendage of royalty (Psalm 32:9; Psalm 66:12), formed a splendid retinue, which would make him "the observed of all observers."

Prepared - As being the king's eldest son, now Amnon was dead; for Chileab, who was his eldest brother, 2-Samuel 3:3, was either dead, or incapable of the government. And this course he knew would draw the eyes of the people to him, and make them conclude that David intended him for his successor.
