Poured it out unto the Lord - To make libations, both of water and wine, was a frequent custom among the heathens. We have an almost similar account in Arrian's Life of Alexander: "When his army was greatly oppressed with heat and thirst, a soldier brought him a cup of water; he ordered it to be carried back, saying, I cannot bear to drink alone while so many are in want, and this cup is too small to be divided among the whole." Tunc poculo pleno sicut oblatum est reddito: Non solus, inquit, bibere sustineo, nec tam exiguum dividere omnibus possum. - Arrian, lib. vi.
The example was noble in both cases, but David added piety to bravery; he poured it out unto the Lord.

And Abishai, the brother of Joab, the son of Zeruiah, was chief among the three,.... Another triumvirate, of which he was the head:

and he lifted up his spear against three hundred, and slew them; Josephus (e) says six hundred; this seems to confirm the reading of Sa2 23:8, that the number eight hundred is right, for if it was only three hundred, Abishai would have been equal to one, even the first, of the former three; which yet is denied him in Sa2 23:19,

and had the name among three; of which he was one; and he had the chief name among them, or was the most famous of them.
