and the LORD spoke to Moses, saying,
“Take the rod; and you and your brother Aaron assemble the congregation and speak to the rock before their eyes, that it may yield its water. You shall thus bring forth water for them out of the rock and let the congregation and their beasts drink.”- Numbers 20:7-8
Then Moses lifted up his hand and struck the rock twice with his rod; and water came forth abundantly, and the congregation and their beasts drank. But YHWH said to Moses and Aaron, “Because you have not believed Me, to treat Me as HOLY in the sight of the sons of Israel, therefore you shall not bring this assembly into the land which I have given them.”- Numbers 20:11-12
Moses disobeyed YHWH by striking the ROCK twice and YHWH refers to the ROCK as HIMSELF
