Numbers 22:16-20

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 whatsoever thou sayest unto me I will do; 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 any thing, small or great.

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

²⁰And God came unto Balaam at night, and said unto him: 'If the men are come to call thee, rise up, go with them; but only the word which I speak unto thee, that shalt thou do.'
