'Feared the Lord' in the Bible

Now one of the wives of a man of the sons of the prophets cried out to Elisha [for help], saying “Your servant my husband is dead, and you know that your servant [reverently] feared the Lord; but the creditor is coming to take my two sons to be his slaves [in payment for a loan].”

They also feared the Lord and appointed from among themselves priests of the high places, who sacrificed for them in the houses of the high places.

They feared the Lord, yet served their own gods, following the custom of the nations from among whom they had been sent into exile.

So these nations [superficially] feared the Lord; they also served their idols, as did their children and their children’s children, just as their fathers did, so do they to this day [the date of this writing].
