9 Afterwards Solomon hearing his father David speak these things, built a wondrous house, and foreseeing Him who was to come into it, said in astonishment, Will God in very deed dwell with men on the earth? Yea, says David by anticipation in the Psalm inscribed For Solomon, wherein is this, He shall come down like rain into a fleece: rain, because of His heavenly nature, and into a fleece, because of His humanity. For rain, coming down into a fleece, comes down noiselessly: so that the Magi, not knowing the mystery of the Nativity, say, Where is He that is born King of the Jews? And Herod being troubled inquired concerning Him who was born, and said, Where is the Christ to be born?
