TSK · Numbers 24:1

So Balaam got up in the morning, and said to the princes of Balak,“Go to your land, for the LORD has refused to permit me to go with you.”

And Balaam said to Balak,“Station yourself here by your burnt offering, while I meet the LORD there.”

For there is no spell against Jacob, nor is there any divination against Israel. At this time it must be said of Jacob and of Israel,‘Look at what God has done!’

Look, these people through the counsel of Balaam caused the Israelites to act treacherously against the LORD in the matter of Peor– which resulted in the plague among the community of the LORD!

So Saul arose and went down to the wilderness of Ziph, accompanied by three thousand select men of Israel, to look for David in the wilderness of Ziph.

But I have a few things against you: You have some people there who follow the teaching of Balaam, who instructed Balak to put a stumbling block before the people of Israel so they would eat food sacrificed to idols and commit sexual immorality.
