"More lovely than the monarch of the sky In wanton Arethusa’s azur’d arms;"

"Speak unto the children of Israel, and bid them that they make them fringes in the borders of their garments, throughout their generations, and that they put upon the fringe of the borders a ribband of blue: ... that ye may remember, and do all my commandments, and be holy unto your God."

"Moses and Aaron, Nadab and Abihu, and the seventy elders of Israel went up and saw the God of Israel. Under his feet was something like a pavement made of lapis lazuli, as bright blue as the sky."

"Above the vault over their heads was what looked like a throne of lapis lazuli, and high above on the throne was a figure like that of a man. I saw that from what appeared to be his waist up he looked like glowing metal, as if full of fire, and that from there down he looked like fire; and brilliant light surrounded him."

"Speake unto the childern of Ysrael and byd them that they make them gardes apon the quarters of their garmetes thorowout their generacions and let them make the gardes of ribandes of jacyncte ... that ye remembre and doo all my commaundmentes and be holy unto youre God."

"Then went up Moses, and Aaron, and Nadab, and Abihu, and seventy of the elders of Israel; and they saw the God of Israel: and there was under his feet as it were a paved work of sapphire stone, and as it were the very heaven for clearness."
