Isaiah 55:3

Hear; hearken attentively and obediently to my counsel; hearing being oft put for obeying, as Deuteronomy 18:15 1 Samuel 15:22,23 Psa 95:7, &c. Your soul shall live, to wit, comfortably and happily; which only is worthy of the name of life. I will make an everlasting covenant with you; that everlasting covenant of grace and peace which I made with Abraham, and his seed the Israelites, I am ready to make it with every one of you thirsting Gentiles. Even the sure mercies of David; even that covenant which was made first with Abraham, and then with David, concerning the exhibition of those glorious and sure mercies or blessings which God hath promised to his people, one and the chief of which mercies was the giving of Christ to die for their sins, and to rise again for their justification. This exposition may receive light and strength by comparing this place with Acts 13:33,34. He mentions David rather than Abraham, either,

1. Because these promises, and especially that great promise, which is the foundation of the rest, concerning Christ and his eternal kingdom, were far more frequently, and expressly, and fully made and revealed to David than they were to Abraham. Or,

2. Because David was a more evident and illustrious type of Christ than Abraham was, as being raised from a mean condition to the highest honour, being made a great and most victorious and righteous king, and the first king of that throne upon which the Messiah was to sit. Or,

3. Because the name of David is not here put personally for the king of that name, but patronymically for the Messiah, who was to be David's Son and successor, and who is therefore called David in the prophetical scriptures, as Jeremiah 30:9 Ezekiel 34:23,24 Ezekiel 37:24,25 Ho 3:5; as Rehoboam upon the same account is called David, 1 Kings 12:16. And this is the more probable, because the next verse, which hath a manifest relation to this verse, is confessedly understood of Christ.
