Then Elijah took twelve stones, according to the number of the tribes of the sons of Jacob, to whom the word of the Lord came, saying, Israel shall be your name. [Gen. 32:28.]
Send men to explore and scout out [for yourselves] the land of Canaan, which I give to the Israelites. From each tribe of their fathers you shall send a man, every one a leader or head among them.
And command them, Take twelve stones out of the midst of the Jordan from the place where the priests' feet stood firm; carry them over with you and leave them at the place where you lodge tonight.
