Psalm 42:7 New English Translation

⁷One deep stream calls out to another^[a] at the sound of your waterfalls;^[b]
all your billows and waves overwhelm me.^[c]

Psalm 42:7 tn Heb “deep calls to deep.” The Hebrew noun תְּהוֹם (t^ehom) often refers to the deep sea, but here, where it is associated with Hermon, it probably refers to mountain streams. The word can be used of streams and rivers (see Deut 8:7; Ezek 31:4).
Psalm 42:7 tn The noun צִנּוֹר (tsinnor, “waterfall”) occurs only here and in 2 Sam 5:8, where it apparently refers to a water shaft. The psalmist alludes to the loud rushing sound of mountain streams and cascading waterfalls. Using the poetic device of personification, he imagines the streams calling out to each other as they hear the sound of the waterfalls.
Psalm 42:7 tn Heb “pass over me” (see Jonah 2:3). As he hears the sound of the rushing water, the psalmist imagines himself engulfed in the current. By implication he likens his emotional distress to such an experience.
