They shall say, "Please fear the Lord." And who were the ones who feared the Lord? It was the household of David, as it says in Psalms 119:63, "I am a companion of all who fear You." And what did David do with them?
As it says in 2 Samuel 7:2, "Here I am, living in a house of cedar, while the ark of God remains in a tent." And what did David say about them in Psalms 89:29-30? "So I will establish his offspring forever, and his throne as the days of heaven. If his children forsake my law and do not walk according to my rules."
Another interpretation of "those who fear the Lord" refers to Pinchas, who killed Zimri and gave his life for the sanctity of God's name, as it says in Numbers 25:11, "Pinchas, the son of Eleazar, the son of Aaron the priest, has turned back my wrath from the people of Israel." And what did God promise him in verse 12? "Therefore say, 'Behold, I give to him my covenant of peace, and it shall be to him and to his descendants after him the covenant of a perpetual priesthood, because he was jealous for his God and made atonement for the people of Israel.'"
Another interpretation of "those who fear the Lord" refers to converts. Regarding Abraham, it says in Genesis 22:12, "Now I know that you fear God." Regarding Obadiah, it says in 1 Kings 18:3, "And Obadiah feared the Lord greatly." Rabbi Chanina said, "The praise of Obadiah is greater than that of Abraham and Joseph, for with Abraham and Joseph, the term 'fear' is used only once, while with Obadiah, it is written, 'Obadiah feared the Lord greatly.'"
Another interpretation of "those who fear the Lord" refers to Hananiah, Mishael, and Azariah, who were saved from the fiery furnace because they trusted in God, as it says in Isaiah 43:5, "Fear not, for I am with you; I will bring your offspring from the east, and from the west I will gather you." And what did God promise them in verse 6? "I will say to the north, Give up, and to the south, Do not withhold; bring my sons from afar and my daughters from the end of the earth."
And not only in this world but also in the world to come, as it says in Psalms 103:17, "But the steadfast love of the Lord is from everlasting to everlasting on those who fear him."
