Am'mah (Hebrew Ammah', אִמָּה, a cubit, as often;. Sept. Α᾿μμά v. r. Α᾿μμάν), a hill "that lieth before Giah by the way of the wilderness of Gibeon:" the sun went down as Joab and Abishai reached this place in pursuit of Abner (2Sa 2:24). The description appears to indicate some eminence immediately east of Gibeon (q.v.). Josephus (Ant. 7, 1, 3) renders, "a place called Ammata" (τόπος τις, ὃν Α᾿μμάταν καλοῦσι); compare the Amta (אִמתָּא) of Jonathan's Targum. Both Symmachus (νάπη) and Theodotion (ὑδραγωγός) agree with the Vulgate in an allusion to some water-course here. It is possibly to the "excavated fountain" "under the high rock," described as near Gibeon (El-Jib) by Robinson (Researches, 2, 136). SEE METHEG-AMMAH.
