Numbers 22:18-20

American Standard Version

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 Jehovah my God, to do less or more. ¹⁹ Now therefore, I pray you, tarry ye also here this night, that I may know what Jehovah will speak unto me more. ²⁰ And 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.
