Numbers 22:19

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

¹⁸  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.

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

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

²¹  And Balaam rose up in the morning, and saddled his ass, and went with the princes of Moab.
