Through the plain - See 1 Samuel 23:24. Bithron is unknown. From the expression all (the) Bithron, it seems likely that it is a tract of country, intersected by ravines lying on the east side of Jordan.

They came to Mahanaim - So they returned to the place whence they set out. See 2 Samuel 2:12. This was the commencement of the civil wars between Israel and Judah, and properly the commencement of the division of the two kingdoms, through which both nations were deluged with blood.

And Abner and his men walked all that night through the plain,.... The plain of Jordan. He marched with his men all night, lest Joab should return, and pursue him, and take vengeance on him for the death of his brother:

and passed over Jordan; at one of the fords of it:

and went through all Bithron; the name of a province or country, as Jarchi, called so perhaps from its being separated from the rest of the tribes of Israel by the river Jordan; some think the mountains of Bether were in this country, Sol 2:17. From Gibeon, where the battle was fought, to Bithron, according to Bunting (o), was twenty eight miles, the which he says was in the tribe of Gad, twenty eight miles from Jerusalem northeastward, lying between Dibon and Jordan:

and they came to Mahanaim: from whence they came, and where they had left Ishbosheth, 2 Samuel 2:8. From Bithron to this place, according to the same writer (p), was sixteen miles.

(o) Travels, &c. p. 145, 146. (p) Ibid.

Abner proceeded with his troops through the Arabah, i.e., the valley of the Jordan, marching the whole night; and then crossing the river, went through the whole of Bithron back to Mahanaim. Bithron is a district upon the eastern side of the Jordan, which is only mentioned here. Aquila and the Vulgate identify it with Bethhoron; but there is no more foundation for this than for the suggestion of Thenius, that it is the same place as Bethharam, the later Libias, at the mouth of the Nahr Hesbn (see at Numbers 32:36). It is very evident that Bithron is not the name of a city, but of a district, from the fact that it is preceded by the word all, which would be perfectly unmeaning in the case of a city. The meaning of the word is a cutting; and it was no doubt the name given to some ravine in the neighbourhood of the Jabbok, between the Jordan and Mahanaim, which was on the north side of the Jabbok.

And Abner and his men walked all that night through the plain, and passed over Jordan, and went through all Bithron, and they came to Mahanaim.

2:25-32 Abner appeals to Joab concerning the miserable consequences of a civil war. Those who make light of such unnatural contests, will find that they are bitterness to all concerned. How easy it is for men to use reason, when it makes for them, who would not use it, if it made against them! See how the issue of things alter men's minds! The same thing which looked pleasant in the morning, at night looked dismal. Those who are most forward to enter into contention, will repent before they have done with it, and had better leave it off before it be meddled with, as Solomon advises. This is true of every sin, oh that men would consider it in time, that it will be bitterness in the latter end! Asahel's funeral is here mentioned. Distinctions are made between the dust of some and that of others; but in the resurrection no difference will be made, but between the godly and ungodly, which will remain for ever.
