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 to me:

¹⁷For I will promote thee to very great honor, and I will do whatever thou sayest to me: come therefore, I pray thee, curse this people for me.

¹⁸And Balaam answered and said to the servants of Balak, If Balak would give me his house full of silver and gold, I could not 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 to me more.

²⁰And God came to Balaam at night, and said to him, If the men come to call thee, rise and go with them; but yet the word which I shall say to thee, that shalt thou perform.
