[51:42] 1 tn For the meaning “multitude” here rather than “tumult” see BDB 242 s.v. הָמוֹן 3.c, where reference is made that this refers to a great throng of people under the figure of an overwhelming mass of waves. The word is used of a multitude of soldiers, or a vast army in 1 Sam 14:16; 1 Kgs 20:13, 18 (cf. BDB 242 s.v. הָמוֹן 3.a for further references).
[51:42] 2 tn Heb “The sea has risen up over Babylon. She has been covered by the multitude of its waves.”
