The Story
The people of Israel were camped on the plains of Moab, right beside the river Jordan, across from the promised land. Balak, the king of Moab, saw how many they were, and he was very afraid. He had heard what God had done for them in Egypt and on their journey. So Balak sent messengers carrying money for rewards, far away to the town of Pethor, to a man named Balaam. Come and curse these people for me, the king begged, and perhaps I can drive them away.
God spoke to Balaam and told him plainly: do not go, and do not curse the people, for God had blessed them. Balaam sent the messengers away. But Balak would not give up. He sent more princes, grander than the first, promising Balaam riches and honour if he would only come. Balaam's heart loved the sound of those rewards. In the end God allowed him to go — but only to speak the very words God gave him.
So Balaam saddled his donkey and set off with the princes of Moab. But God was angry with Balaam's greedy heart, and the angel of the LORD stood in the road with a sword in his hand. Balaam could not see the angel — but the donkey could! She turned aside into a field, and Balaam beat her to get her back on the road. A little later the angel stood in a narrow path between two walls; the donkey pressed against the wall and crushed Balaam's foot, and he beat her again. The third time, the angel stood in a place so narrow there was no room to turn at all, and the donkey lay down under Balaam. Balaam beat her with his staff.
Then God did something that had never happened before: He opened the donkey's mouth, and she spoke! "What have I done unto thee, that thou hast smitten me these three times?" Balaam, too angry even to be surprised, answered that he wished he had a sword to kill her. Then God opened Balaam's eyes — and there stood the angel of the LORD with his sword drawn! The angel asked him, "Wherefore hast thou smitten thine ass these three times?" and told him the truth: the donkey had turned aside three times, and if she had not, the angel would have killed Balaam and saved the donkey alive. The donkey Balaam had beaten had saved his life.
Balaam bowed right down to the ground and said he had sinned. He still went on to Balak, but he told the king honestly: "the word that God putteth in my mouth, that shall I speak." Three times Balak took Balaam up on high hills to curse Israel — and three times Balaam opened his mouth, and out came blessings instead, for God would not let His people be cursed. Balaam blessed their camp: "How goodly are thy tents, O Jacob, and thy tabernacles, O Israel!" And the words of our memory verse are part of that blessing: God is not a man, that He should lie. Balak clapped his hands in anger and sent Balaam home with nothing. God had protected His people from a danger they never even saw — because God's word never, ever fails.
