In the restoration the Gentiles will come to Israel to entreat the favor, the grace, of Jehovah, and the children of Israel will be priests to them (vv. 20-23; Isa. 2:2-3; 61:6). After the Jews are saved at the Lord’s coming back (Zech. 12:10; Rom. 11:26-27), they will become the priests to teach all the repentant nations. By that time the entire nation of Israel will be a priesthood, thus fulfilling God’s original intention expressed in Exo. 19:6. They will teach the Gentiles, the nations, to know God’s way and God’s person, and they will teach them to worship and serve God. As priests, they will bring the nations into the presence of God that they may be enlightened, corrected, and favored with all the riches of God. The prophecy in vv. 20-23 was an encouraging word spoken to the children of Israel. See note Isa. 2:32.
