I agree with the idea of many different spirits and [little g--gods] out there altering and influencing the world.
But, I have used metal coat hangers to locate the metal water lines on our property. Nothing magical about that.
Simply saying "it works" doesn't explain why it works. Nor does it disprove that it works "by magic" or via a supernatural force.
Moses used a rod and with our 'God' he unleashed water. That is not blasphemy nor did I infer that it was divining.
The context in which you used the quote (a thread on divining) certainly made it look like you were using it as an example of divining found in the Bible. If not, they why did you quote the line?
Place the line in context and it seems to have nothing to do with divination or dowsing.
"Now there was no water for the community, and the people gathered in opposition to Moses and Aaron. 3 They quarreled with Moses and said, “If only we had died when our brothers fell dead before the Lord! 4 Why did you bring the Lord’s community into this wilderness, that we and our livestock should die here? 5 Why did you bring us up out of Egypt to this terrible place? It has no grain or figs, grapevines or pomegranates. And there is no water to drink!”
6 Moses and Aaron went from the assembly to the entrance to the tent of meeting and fell facedown, and the glory of the Lord appeared to them. 7 The Lord said to Moses, 8 “Take the staff, and you and your brother Aaron gather the assembly together. Speak to that rock before their eyes and it will pour out its water. You will bring water out of the rock for the community so they and their livestock can drink.”
9 So Moses took the staff from the Lord’s presence, just as he commanded him. 10 He and Aaron gathered the assembly together in front of the rock and Moses said to them, “Listen, you rebels, must we bring you water out of this rock?” 11 Then Moses raised his arm and struck the rock twice with his staff. Water gushed out, and the community and their livestock drank.
12 But the Lord said to Moses and Aaron, “Because you did not trust in me enough to honor me as holy in the sight of the Israelites, you will not bring this community into the land I give them.”"
God did not command Moses to use his rod to locate water--there was no divining (searching for water) with a stick. God told Moses exactly where it was.
God also did not tell Moses to use his rod to bring forth the water. God told Moses to speak to the rock, and it would bring forth water. God, in fact, gets angry at Moses for using his rod to bring forth the water (by hitting the rock--notice again there is no dowsing with a stick going on to locate the water source).
And yes, taking scripture--God's word--out of context to imply it says something it doesn't (twisting scripture) is a form of blasphemy.
