And when Joab was come out from David, he sent messengers after Abner, which brought him again from the well of Sirah: but David knew it not. (2 Samuel 3:26)
Without the knowledge but probably in the name of David.
Well of Sirah.
Or “cistern of Sirah.” The location of this well is not positively known. Some have identified it with ‘Ain Sārah, about 1 1/2 mi. (2.4 km.) north of Hebron. The site seems somewhat unlikely, for in such a case Abner would have just left Hebron when Joab arrived. Others have identified it with Ṣîret el-Bella‘, a mountaintop 2.7 mi. (4.3 km.) north of Hebron, where the ruins of a tower are to be seen.
