Lead. This is one of the most common of metals, found generally in veins of rocks, though seldom in a metallic state, and most commonly in combination with sulphur. It was early known to the ancients, and the allusions to it in Scripture indicate that the Hebrews were well acquainted with its uses. The rocks in the neighborhood of Sinai yielded it in large quantities, and it was found in Egypt. In Job 19:24 the allusion is supposed to be to the practice of carving inscriptions upon stone and pouring molten lead into the cavities of the letters, to render them legible and at the same time preserve them from the action of the air.
