(Exodus 32:16)); also stones and signets (Ex. 28:11,21,3611With the work of an engraver in stone, like the engravings of a signet, shalt thou engrave the two stones with the names of the children of Israel: thou shalt make them to be set in ouches of gold. (Exodus 28:11)

(Job 19:24); Acts 17:2929Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device. (Acts 17:29)).
