Jacob’s ladder. A Jacob’s ladder is a ship’s wood-runged rope or chain ladder primarily used to let people ascend from or de- scend to smaller boats alongside. The name is also given to a steep flight of steps up a cliff, an herb or flower in the shape of a ladder, and a burglar’s ladder. All take their name from the ladder seen by the biblical patriarch Jacob in a vision (Gen. 28:12–13), the ladder in the dream symbolizing the hopes of Jacob for his descendants. |
