Numbers 23:3-4

3Then Balaam said to Balak, ‘Stand next to your burnt offering. I will go to see if the Lord will come to meet me. If he shows something to me, I will tell you about it.’ Then Balaam went to the top of a hill where there were no trees.

4Balaam said to the Lord, ‘I made seven altars. On each altar, I have offered a bull and a male sheep.’
