[14:19] 1 sn B. Jacob (Exodus, 400-401) makes a good case that there may have been only one pillar, one cloud; it would have been a dark cloud behind it, but in front of it, shining the way, a pillar of fire. He compares the manifestation on Sinai, when the mountain was on fire but veiled by a dark cloud (Deut 4:11; 5:22). See also Exod 13:21; Num 14:14; Deut 1:33; Neh 9:12, 19; Josh 24:7; Pss 78:14; 105:39.
[14:21] 2 tn Or “drove the sea back” (NIV, NCV, NRSV, TEV). The verb is simply the Hiphil of הָלַךְ (halakh, “to walk, go”). The context requires that it be interpreted along the lines of “go back, go apart.”
