"When your children shall ask you in time to come, saying, what mean these twelve stones, then you shall tell them how you made it over."
Joshua 4: 21-22 is the verse inscribed on this stone monument near the Edmund Pettus Bridge. It refers to a miracle of God in the book of Joshua in The Bible. The Israelites erected a monument of 12 stones, representing the 12 tribes of Israel, after they crossed the Jordan River into the Promised Land. The monument was placed to remind them of the amazing miracle of how the Lord dried the river until they all had crossed. God had performed a similar miracle 40 years before with the Red Sea.
The verse is used here to remind future generations of how the right to vote was won for all Americans. It is significant that churches were used as meeting places for much of the voting rights and other civil rights activism.
