Give ear and come to me;
    listen, that you may live.
I will make an everlasting covenant with you,
    my faithful love promised to David.
4 See, I have made him a witness to the peoples,
    a ruler and commander of the peoples.
5 Surely you will summon nations you know not,
    and nations you do not know will come running to you,
because of the Lord your God,
    the Holy One of Israel,
    for he has endowed you with splendour.’

To all who come to God, in response to His generous offer, He promises He will make an ”everlasting covenant” with them. This is a continuation of the same covenant God made with David when He promised him an everlasting throne- a promise ultimately fulfilled in Jesus

One thing that happens when we immerse ourselves in the Scriptures – truly humbling ourselves before them, listening to God and seeking to obey Him – is this: we are ‘changed from glory into glory’. The Lord makes His people beautiful with the beauty of Jesus as they look to Him and on Him (2 Corinthians 3:18), Furthermore, this beauty attracts others. The Lord’s people become a ”city set on a hill” (Matt.5:14).

‘These words, of course, apply not only to the post-exilic Jerusalem of the Old Testament but also to the church of Christ in the New Testament and ultimately to the new Jerusalem where Christ will reign supreme forever (Revelation 21:1-5).’ Tom Hale: ‘Applied Old Testament Commentary’, p.1059.
