Charles H. Spurgeon on Psalms 29:7

The voice of the Lord divideth the flames of fire. The voice of the Lord is here said to divide the flames; literally, to hew out flames, (latomein flav). The Septuagint has (diakoptei floga puroz). In the words of Gensenius, "The voice of Jehovah cutteth out flames of fire, "i.e., "sendeth out divided flames of fire." This is (as Theodoret has observed) very descriptive of the divine action at Pentecost, sending forth divided flames, like "tela trisulca, "in the tongues of fire which were divided off from one heavenly source or fountain of flame, and sat upon the heads of the apostles, and which filled them with the fire of holy zeal and love. Christopher Wordsworth.
