Numbers 22:17 KJV

15And Balak sent yet again princes, more, and more honourable than they.

16And 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:

17For 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.

18And 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.

19Now therefore, I pray you, tarry ye also here this night, that I may know what the LORD will say unto me more.
