I must do whatever the Lord says

Numbers 22:41-23:26
Balak took Balaam up to Bamoth Baal, and from there he could see the outskirts(郊區) of the Israelite camp.
Balaam answered,"Must I not speak what the Lord puts in my mouth?"
Then Balak said to him, "Come with me to another pace where you can see them; you will not see them all but only the outskirts of their camp."
Balaam answered, "Did I not tell you I must do whatever the Lord says?"
And neither bribe nor threat will budge(讓步) him from the truth as God reveals it to him.
Why?
Balak try to find some way that God will let him said blessing word to Moab and cursing word to Israelite, then he can gain much treasure. But the Lord didn't allowed him speak other word which was not God's meaning.
I must speak what the Lord puts in my mouth. And I tell you I must do whatever the Lord says.
Standing position does not change the word of the Lord.
How?
I must do whatever the Lord says, speak what the Lord puts in my mouth.
