Shammah the Harodite, Elika the Harodite,

Wesley's Notes

23:25 Harodite - In 1Chron 11:27, Shammoth the Harorite. Concerning which, and other changes of the names, which will be observed, by comparing this catalogue with that, it will be sufficient to suggest, that the same names of persons, or places, are differently pronounced according to the different dialects of divers places or ages. That one man had often two names. That David had more worthies than those here mentioned; and as some of these were slain in the former part of David's reign, as Asahel was; so others came up in their stead; and some were added to this number, as appears from 1Chron 11:10 - 47, where they are named, but not numbered, as they were here; and where there is a greater number than is here expressed.

Matthew Henry's Concise Commentary

23:8-39 David once earnestly longed for the water at the well of Bethlehem. It seems to be an instance of weakness. He was thirsty; with the water of that well he had often refreshed himself when a youth, and it was without due thought that he desired it. Were his valiant men so forward to expose themselves, upon the least hint of their prince's mind, and so eager to please him, and shall not we long to approve ourselves to our Lord Jesus, by ready compliance with his will, as shown us by his word, Spirit, and providence? But David poured out the water as a drink-offering to the Lord. Thus he would cross his own foolish fancy, and punish himself for indulging it, and show that he had sober thoughts to correct his rash ones, and knew how to deny himself. Did David look upon that water as very precious which was got at the hazard of these men's blood, and shall not we much more value those benefits for purchasing which our blessed Saviour shed his blood? Let all beware of neglecting so great salvation.
