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.

LEAD, a metal known to the ancients from a very early period, and alluded to in Ex 15:10 on account of its weight. It is mentioned several times in Scripture as entering into the process of purifying more precious metals, Jer 6:29; Eze 22:18, Ruth 4:20; for which purpose quicksilver is now used. The words of Job 19:24, "That they were graven with an iron pen and lead in the rock for ever!" refer to the custom of pouring molten lead into letters carved in the rock in order to make them more striking to the eye.
