'Fear the Lord' in the Bible

so that all the peoples of the earth may know [without any doubt] and acknowledge that the hand of the Lord is mighty and extraordinarily powerful, so that you will fear the Lord your God [and obey and worship Him with profound awe and reverence] forever.”

“Now, therefore, fear the Lord and serve Him in sincerity and in truth; remove the gods which your fathers served on the other side of the [Euphrates] River and in Egypt, and serve the Lord.
