Articles of agreement among men are usually sealed, that the covenants may be the more solemn, and the performances of the covenants the more sure, to mutual satisfaction. God therefore, being willing more abundantly to show to the heirs of promise the immutability of his councils, has confirmed his covenant by a seal (Heb 6:17), which makes the foundations we build on stand sure, Ti2 2:19. The seal of this covenant of nature was natural enough; it was the rainbow, which, it is likely, was seen in the clouds before, when second causes concurred, but was never a seal of the covenant till now that it was made so by a divine institution. Now, concerning this seal of the covenant, observe, 1. This seal is affixed with repeated assurances of the truth of that promise of which it was designed to be the ratification: I do set my bow in the cloud (Gen 9:23); it shall be seen in the cloud (Gen 9:14), that the eye may affect the heart and confirm the faith; and it shall be the token of the covenant (Gen 9:12, Gen 9:13), and I will remember my covenant, that the waters shall no more become a flood, Gen 9:15. Nay, as if the Eternal Mind needed a memorandum, I will look upon it, that I may remember the everlasting covenant, Gen 9:16. Thus here is line upon line, that we might have sure and strong consolation who have laid hold of this hope. 2. The rainbow appears when the clouds are most disposed to wet, and returns after the rain; when we have most reason to fear the rain prevailing, then God shows this seal of the promise that it shall not prevail. Thus God obviates our fears with such encouragements as are both suitable and seasonable. 3. The thicker the cloud the brighter the bow in the cloud. Thus, as threatening afflictions abound, encouraging consolations much more abound, Co2 1:5. 4. The rainbow appears when one part of the sky is clear, which intimates mercy remembered in the midst of wrath; and the clouds are hemmed as it were with the rainbow, that they may not overspread the heavens, for the bow is coloured rain or the edges of a cloud gilded. 5. The rainbow is the reflection of the beams of the sun, which intimates that all the glory and significancy of the seals of the covenant are derived from Christ the Sun of righteousness, who is also described with a rainbow about his throne (Rev 4:3), and a rainbow upon his head (Rev 10:1), which intimates, not only his majesty, but his mediatorship. 6. The rainbow has fiery colours in it, to signify that though God will not again drown the world, yet, when the mystery of God shall be finished, the world shall be consumed by fire. 7. A bow bespeaks terror, but this bow has neither string nor arrow, as the bow ordained against the persecutors has (Psa 7:12, Psa 7:13), and a bow alone will do little execution. It is a bow, but it is directed upwards, not towards the earth; for the seals of the covenant were intended to comfort, not to terrify. 8. As God looks upon the bow, that he may remember the covenant, so should we, that we also may be ever mindful of the covenant, with faith and thankfulness.

This is the token - אות oth, The Divine sign or portent: The bow shall be in the cloud. For the reasons above specified it must be there, when the circumstances already mentioned occur; if therefore it cannot fail because of the reasons before assigned, no more shall my promise; and the bow shall be the proof of its perpetuity.

Both the Greeks and Latins, as well as the Hebrews, have ever considered the rainbow as a Divine token or portent; and both of these nations have even deified it, and made it a messenger of the gods.

Homer, Il. xi., ver. 27, speaking of the figures on Agamemnon's breastplate, says there were three dragons, whose colors were

- - ιρισσιν εοικοτες, ἁς τε Κρονων.

Εν νεφεΐ στηριξε, τερας μεροπων ανθρωπων.

"like to the rainbow which the son of Saturn has placed in the cloud as a Sign to mankind," or to men of various languages, for so the μεροπων ανθρωπων of the poet has been understood. Some have thought that the ancient Greek writers give this epithet to man from some tradition of the confusion and multiplication of tongues at Babel; hence in this place the words may be understood as implying mankind at large, the whole human race; God having given the rainbow for a sign to all the descendants of Noah, by whom the whole earth was peopled after the flood. Thus the celestial bow speaks a universal language, understood by all the sons and daughters of Adam. Virgil, from some disguised traditionary figure of the truth, considers the rainbow as a messenger of the gods. Aen. v., ver. 606:

Irim de caelo misit Saturnia Juno.

"Juno, the daughter of Saturn, sent down the rainbow from heaven;" and again, Aen. ix., ver. 803: -

aeriam caelo nam Jupiter Irim Demisit.

"For Jupiter sent down the ethereal rainbow from heaven."

It is worthy of remark that both these poets understood the rainbow to be a sign, warning, or portent from heaven."

As I believe the rainbow to have been intended solely for the purpose mentioned in the text, I forbear to make spiritual uses and illustrations of it. Many have done this, and their observations may be very edifying, but they certainly have no foundation in the text.

And God said to Noah, this is the token of the covenant,.... Which is repeated for the greater confirmation and certainty of it, since the fears of men would be apt to run very high, especially while the flood was fresh in memory:

which I have established between me and all flesh that is upon the earth: see Gen 9:9, it is highly probable, that from the rainbow being the token of the covenant between God and Noah, and the creatures, sprung the fable of the Chinese concerning their first emperor, Fohi, who seems to be the same with Noah, and whom they call the son of heaven, and say he had no father; which is this, that his mother, walking on the bank of a lake near Lanthien, in the province of Xensi, trod upon a large footstep of a man impressed upon the sand, and from thence, being surrounded with the rainbow, conceived and brought forth Fohi (x).

RAINBOW. (Gen. 9:8-29)

I do set my bow in the cloud--set, that is, constitute or appoint. This common and familiar phenomenon being made the pledge of peace, its appearance when showers began to fall would be welcomed with the liveliest feelings of joy.
