2 Samuel 22:48 tn Heb “The God is the one who grants vengeance to me.” The plural form of the noun “vengeance” indicates degree here, suggesting complete vengeance or vindication. In the ancient Near East military victory was sometimes viewed as a sign that one’s God had judged in favor of the victor, avenging and/or vindicating him. See, for example, Judg 11:27, 32-33, 36.
2 Samuel 22:48 tn Heb “and [is the one who] brings down nations beneath me.”
