The tradition of casting lots is in the Bible several times. They are thought to have been used in 1 Samuel.
The primary reason for casting lots was to render an impartial, unbiased decision on important matters. Once they were cast, no one could argue that the decision was the result of human intervention like nepotism, politics, favouritism, and so on. This practice would be the same as throwing dice or flipping a coin we commonly use today. In ancient times, they used varying means to cast lots, depending on the place and local customs, such as coins, polished sticks, cards, dice, and so on.
