Do Not Be Ignorant
Paul opens Chapter 10 by telling the Corinthian Christians to not be ignorant to not be ag-no-eh-o which means the following:
The Greek word for "ignorant" - ἀãíïέù, agnoeō, ag-no-eh'-o. Not to know (through lack of information or intelligence); by implication to ignore (through disinclination)--(be) ignorant (-ly), not know, not understand, unknown (From Strong's Greek and Hebrew definitions).
The Message reads this way in verses 1-5:
Remember our history, friends, and be warned. All our ancestors were led by the providential Cloud and taken miraculously through the Sea. They went through the waters, in a baptism like ours, as Moses led them from enslaving death to salvation life. They all ate and drank identical food and drink, meals provided daily by God. They drank from the Rock, God's fountain for them that stayed with them wherever they were. And the Rock was Christ. But just experiencing God's wonder and grace didn't seem to mean much--most of them were defeated by temptation during the hard times in the desert, and God was not pleased.
