And it shall come to pass, if they will diligently learn the
ways of my people
Not their evil ways of sin or superstition, they sometimes stray into; but the ways which God has prescribed to them, and has directed them to walk in, and in which they do walk; and which are to be learned of the Lord, by a diligent attendance with his people on his word and ordinances; see ( Isaiah 2:3 ) : to swear by my name, the Lord liveth;
that is, to worship and serve the living God, a self-existent Being, who has life in himself, and of himself, and not another; and is the fountain, author, and giver of natural life to all creatures, and spiritual and eternal life to his true worshippers: swearing is here put for the whole of religious worship, as in ( Deuteronomy 6:13 ) : (as they taught my people to swear by Baal;)
to worship him, and other idols: then shall they be built in the midst of my people;
become part of the spiritual building the church; being laid upon the same foundation of the apostles and prophets, and built up a holy temple; a spiritual house for the Lord to dwell in; partaking of the same privileges and ordinances as the people of God; being fellow heirs, and of the same body, and partakers of the promise in Christ by the Gospel, ( Ephesians 2:20 Ephesians 2:21 ) ( 3:6 ) , it denotes the settlement and establishment of the Gentiles with the Jews in a Gospel church state. So the Targum,
``and they shall be established in the midst of my people.''
