1 Corinthians 10:7

Neither be ye idolaters, as were some of them; as it is written, The people sat down to eat and drink, and rose up to play (KJV)

Then: Example #1 after verse 6: Written in Exodus 32:6, verse refers to the idolaters, blessed Israelites, with split minds made a golden calf while Moses was talking to God. Paul warns the Corinthians that if the Israelites could lose their place during the trip to the Promised Land, anyone can. They are eating at the communion table and going out to play - on the wrong temple grounds.

Now: Same message - if the Israelites could go astray, so can today's believers.
