'Twelve' in the Bible

Then they came to Elim where there were twelve springs of water and seventy date palms, and they camped there beside the waters.

Moses wrote down all the words of the Lord. Then he arose early in the morning, and built an altar at the foot of the mountain with twelve pillars for the twelve tribes of Israel.

The stones shall be according to the names of the sons of Israel: twelve, according to their names; they shall be like the engravings of a seal, each according to his name for the twelve tribes.

The stones were corresponding to the names of the sons of Israel; they were twelve, corresponding to their names, engraved with the engravings of a signet, each with its name for the twelve tribes.
