Numbers 22:15-19

And Balak sent yet again princes, more, and more honourable than they.

And they came to Balaam, and said to him, Thus saith Balak the son of Zippor, Let nothing, I pray thee, hinder thee from coming unto me:

For I will promote thee unto very great honour, and I will do whatsoever thou sayest unto me: come therefore, I pray thee, curse me this people.

And Balaam answered and said unto the servants of Balak, If Balak would give me his house full of silver and gold, I cannot go beyond the word of the LORD my God, to do less or more.

Now therefore, I pray you, tarry ye also here this night, that I may know what the LORD will say unto me more.
