5 Then the LORD told Moses, “Go over in front of the people and take some of the elders of Israel with you. Take in your hand the staff with which you struck the Nile, and go.
6 I’ll be standing there in front of you on the rock at Horeb. You are to strike the rock and water will come out of it, so the people can drink.” Moses did this in front of the elders of Israel.

Deuteronomy 18:9-12
9 Detestable Practices“When you enter the land that the LORD your God is about to give you, don’t learn the detestable practices of those nations there.
10 There must never be found among you anyone who sacrifices his son or daughter in fire, practices divination, interprets omens, practices sorcery,
11 casts spells, or who is a medium, an occultist, or a necromancer.
12 Whoever practices these things is detestable to the LORD, and the LORD your God will expel them before you because of these things.
Hosea 4:12
12 My people seek counsel from their piece of wood, and their diviner’s rod speaks to them. For a spirit of prostitution causes them to go astray; in their immorality they desert their God.
