Numbers 23:15-19

¹⁵And Balaam said to Balac, Stand by thy sacrifice, and I will go to enquire of God.

¹⁶And God met Balaam, and put a word into his mouth, and said, Return to Balac, and thus shalt thou speak.

¹⁷And he returned to him: and he also was standing by his whole-burnt-sacrifice, and all the princes of Moab with him; and Balac said to him, What has the Lord spoken?

¹⁸And he took up his parable, and said, Rise up, Balac, and hear; hearken as a witness, thou son of Sepphor.

¹⁹God is not as man to waver, nor as the son of man to be threatened; shall he say and not perform? shall he speak and not keep to his word?
