The occasion of this Psalm is a thunderstorm; it is not, however, limited to the outward natural phenomena, but therein is perceived the self-attestation of the God of the redemptive history. Just as in the second part of Psa 19:1-14 the God of the revelation of salvation is called יהוה seven times in distinction from the God revealed in nature, so in this Psalm of thunders, קול ה is repeated seven times, so that it may be called the Psalm of the hepta' brontai' (Rev 10:3.). During the time of the second Temple, as the addition to the inscription by the lxx ἐξοδίου (ἐξόδου) σκηνῆς (= σκηνοπηγίας) seems to imply, it was sung on the Shemini Azereth, the last day (ἐξόδιον, Lev 23:36) of the feast of tabernacles. Between two tetrastichs, in each of which the name יהוה occurs four times, lie three pentastichs, which, in their sevenfold קול ה, represent the peals of thunder which follow in rapid succession as the storm increases in its fury.
