Isaiah 44:1 - Joseph Benson’s Commentary on the Old and New Testaments

Yet now hear, O Jacob Although I have chastised thee for thy sins, and had just cause utterly to destroy thee, yet in judgment I will remember mercy, and will still own thee for my servant and chosen people. Thus saith the Lord, that formed thee from the womb “He speaks of the Jewish people under the character of a single person; and as God sometimes designed certain persons for particular offices, from their birth, or conception, so he set apart the posterity of Abraham to be his people from the very original of the family;” and formed and fashioned them for himself, by laws, ordinances, teachers, promises, threatenings, corrections, and many other ways. Jesurun is another name for Jacob or Israel, given to them by Moses, Deuteronomy 32:15, (where see the note.) and 33:5, 26.
