SEV Biblia, Chapter 2:15
Entonces se levantaron, y en número de doce, pasaron de Benjamín de la parte de Is-boset hijo de Saúl; y doce de los siervos de David.
John Gill's Bible Commentary
Ver. 15. Then there arose and went over by number twelve of Benjamin , etc.] Whom Abner had picked out of that tribe, being his own, and whom he knew to be stout and courageous men, and closely attached to him. It seems by this as if Abner’s men, [which pertained to] Ishbosheth, the son of Saul , passed over the pool of Gibeon unto Joab’s men; so forward were they to engage in this duel, and it makes it still more appear that they were the aggressors: and twelve of the servants of David ; of his army under Joab, whom Joab either selected, or they, offered themselves as willing to engage with the twelve that were come over.
Matthew Henry Commentary
Verses 8-17 - The nation in general refused David. By this the Lord trained up his servant for future honour and usefulness; and the tendency of tru godliness was shown in his behaviour while passing through variou difficulties. David was herein a type of Christ, whom Israel would no submit to, though anointed of the Father to be a Prince and a Saviou to them. Abner meant, Let the young men fight before us, when he said Let them play before us: fools thus make a mock at sin. But he is unworthy the name of a man, that can thus trifle with human blood.
