Genesis 9:13

Verse 13. My rain bow. This had been from the beginning; but it was not before appointed for a sign that the earth should no more be destroyed by water. It is styled God’s bow, on account of its beauty and grandeur. Menochius. Ecclus 43:12.—“As the rain-bow, which makes its appearance in the clouds, borrows all its effulgence from the sun, so those only who acknowledge the glory of Christ in God’s clouds, and do not seek their own glory, will escape destruction in the deluge.” Saint Augustine c. Faust. ii. 21.
