Numbers 23:3-7

³And Balaam said unto Balak: 'Stand by thy burnt-offering, and I will go; peradventure the LORD will come to meet me; and whatsoever He showeth me I will tell thee.' And he went to a bare height.

⁴And God met Balaam; and he said unto Him: 'I have prepared the seven altars, and I have offered up a bullock and a ram on every altar.'

⁵And the LORD put a word in Balaam's mouth, and said: 'Return unto Balak, and thus thou shalt speak.'

⁶And he returned unto him, and, lo, he stood by his burnt-offering, he, and all the princes of Moab.

⁷And he took up his parable, and said: From Aram Balak bringeth me, the king of Moab from the mountains of the East: 'Come, curse me Jacob, and come, execrate Israel.'
