'Fear the Lord' in the Bible

‘They do not say in their heart,“Let us now fear the Lord our God,Who gives rain in its season,Both the autumn rain and the spring rain,Who keeps for usThe appointed weeks of the harvest.”

Did Hezekiah king of Judah and all Judah put him to death? Did he not fear the Lord and entreat the favor of the Lord, and the Lord changed His mind about the misfortune which He had pronounced against them? But we are committing a great evil against ourselves.”
