'Seal' in the Bible

Make a ship of gopher wood. You shall make rooms in the ship, and shall seal it inside and outside with pitch.

and he saith, 'What is the pledge that I give to thee?' and she saith, 'Thy seal, and thy ribbon, and thy staff which is in thy hand;' and he giveth to her, and goeth in unto her, and she conceiveth to him;

She is brought out, and she hath sent unto her husband's father, saying, 'To a man whose these are, I am pregnant;' and she saith, 'Discern, I pray thee, whose are these -- the seal, and the ribbons, and the staff.'
