Numbers 22:15-21 - Balaam Accompanies The Moabite Princes
15 And Balak sent yet again rulers, more, and more honorable than they. 16 And they came to Balaam, and said to him, Thus says Balak the son of Zippor, Let nothing, I pray thee, hinder thee from coming to me. 17 For I will promote thee to very great honor, and whatever thou say to me I will do. Come therefore, I pray thee, curse this people for me.
18 And Balaam answered and said to the servants of Balak, If Balak would give me his house full of silver and gold, I cannot go beyond the word of 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 LORD will speak to me more.
20 And God came to Balaam at night, and said to him, If the men come to call thee, rise up, go with them, but only the word which I speak to thee, that shall thou do. 21 And Balaam rose up in the morning, and saddled his donkey, and went with the rulers of Moab.
