Numbers 23:1-3

1Balaam said to King Balak, ‘Build seven altars here for me. Prepare seven bulls and seven male sheep.’

2Balak did this. Balaam and Balak then offered a bull and a male sheep on each altar as a sacrifice.

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.
