When he uttereth his voice. The continuous activity of God is exhibited in the phenomena of nature (see Amos 5:8; 9:5, 6). The psalmist, too, saw in the thunderstorm a display of the majestic power of God. He termed thunder the voice of God (see on Ps. 29:3).
Multitude. Heb. hamon, “commotion,” “tumult,” and hence “multitude,” or “crowd.”
Vapours. Heb. nesi’im, defined as “damp fog,” used in this sense only here and in Jer. 51:16 and Ps. 135:7, which are largely parallel, and in Prov. 25:14, where it is translated “clouds.”
With rain. Literally, “for the rain.”
