'Unsuspecting' in the Bible

Then the five men departed, and came to La'ish, and saw the people who were there, how they dwelt in security, after the manner of the Sido'nians, quiet and unsuspecting, lacking nothing that is in the earth, and possessing wealth, and how they were far from the Sido'nians and had no dealings with any one.

When you go, you will come to an unsuspecting people. The land is broad; yea, God has given it into your hands, a place where there is no lack of anything that is in the earth."

And taking what Micah had made, and the priest who belonged to him, the Danites came to La'ish, to a people quiet and unsuspecting, and smote them with the edge of the sword, and burned the city with fire.

For such serve not our Lord Christ, but their own belly, and by good words and fair speeches deceive the hearts of the unsuspecting.
