Divideth the flames of fire - Margin, "cutteth out." The Hebrew word - חצב châtsab - means properly "to cut, to hew, to hew out;" as, for example, stones. The allusion here is undoubtedly to lightning; and the image is either that it seems to be cut out, or cut into tongues and streaks - or, more probably, that the "clouds" seem to be cut or hewed so as to make openings or paths for the lightning. The eye is evidently fixed on the clouds, and on the sudden flash of lightning, as if the clouds had been "cleaved" or "opened" for the passage of it. The idea of the psalmist is that the "voice of the Lord," or the thunder, seems to cleave or open the clouds for the flames of fire to play amidst the tempest. Of course this language, as well as that which has been already noticed Psalm 29:5, must be taken as denoting what "appears" to the eye, and not as a scientific statement of the reality in the case. The rolling thunder not only shakes the cedars, and makes the lofty trees on Lebanon and Sirion skip like a calf or a young unicorn, but it rends asunder or cleaves the clouds, and cuts out paths for the flames of fire.

Divideth the flames of fire - The forked zigzag lightning is the cause of thunder; and in a thunder-storm these liahtnings are variously dispersed, smiting houses, towers, trees, men, and cattle, in different places.

The voice of the Lord divideth the flames of fire. Or "cutteth with flames of fire" (e); that is, the thunder breaks through the clouds with flames of fire, or lightning, as that is sometimes called, Psalm 105:32; and with which it cleaves asunder trees and masts of ships, cuts and hews them down, and divides them into a thousand shivers. Some refer this, in the figurative and mystical sense, to the giving of the law on Mount Sinai (f), on which the Lord descended in fire, and from his right hand went a fiery law; but rather this may be applied to the cloven or divided tongues of fire which sat upon the disciples on the day of Pentecost, as an emblem of the extraordinary gifts of the Spirit bestowed on them; though it seems best of all, as before, to understand this of the voice of Christ in the Gospel, which cuts and hews down all the goodliness of men, and lays them to the ground, Hosea 6:5; and is of a dividing nature, and lays open all the secrets of the heart, Hebrews 4:12; and, through the corruption or human nature, is the occasion of dividing one friend from another, Luke 12:51; and like flames of fire it has both light and heat in it; it is the means of enlightening men's eyes to see their sad estate, and their need of Christ, and salvation by him; and of warming their souls with its refreshing truths and promises, and of inflaming their love to God and Christ, and of setting their affections on things above, and of causing their hearts to burn within them.

(e) "caedit cum flammis ignis", Cocceius, Gejerus. (f) Jarchi in loc.

The voice of the LORD divideth the {e} flames of fire.

(e) It causes the lightnings to shoot and glide.

29:7 The flames - The lightnings.

divideth: Heb. cutteth out

7. divideth-literally, "hews off." The lightning, like flakes and splinters hewed from stone or wood, flies through the air.

29:1-11 Exhortation to give glory to God. - The mighty and honourable of the earth are especially bound to honour and worship him; but, alas, few attempt to worship him in the beauty of holiness. When we come before him as the Redeemer of sinners, in repentance faith, and love, he will accept our defective services, pardon the sin that cleaves to them, and approve of that measure of holiness which the Holy Spirit enables us to exercise. We have here the nature of religious worship; it is giving to the Lord the glory due to his name. We must be holy in all our religious services, devoted to God, and to his will and glory. There is a beauty in holiness, and that puts beauty upon all acts of worship. The psalmist here sets forth God's dominion in the kingdom of nature. In the thunder, and lightning, and storm, we may see and hear his glory. Let our hearts be thereby filled with great, and high, and honourable thoughts of God, in the holy adoring of whom, the power of godliness so much consists. O Lord our God, thou art very great! The power of the lightning equals the terror of the thunder. The fear caused by these effects of the Divine power, should remind us of the mighty power of God, of man's weakness, and of the defenceless and desperate condition of the wicked in the day of judgment. But the effects of the Divine word upon the souls of men, under the power of the Holy Spirit, are far greater than those of thunder storms in the nature world. Thereby the stoutest are made to tremble, the proudest are cast down, the secrets of the heart are brought to light, sinners are converted, the savage, sensual, and unclean, become harmless, gentle, and pure. If we have heard God's voice, and have fled for refuge to the hope set before us, let us remember that children need not fear their Father's voice, when he speaks in anger to his enemies. While those tremble who are without shelter, let those who abide in his appointed refuge bless him for their security, looking forward to the day of judgment without dismay, safe as Noah in the ark.
