Macbeth did. While the story of Macbeth is one of tragedy, his words "the very firstlings of my heart" have been interpreted as a reference to blood relatives. The word "firstling" means "youngest or lowest in order of birth." Thus, this phrase could be read as saying that his love for his family was equal to that of any other man. This interpretation comes from later writers who commented on the play. However, it has also been suggested that "the very firstlings of my heart" could mean his children. The word "firstling" can also be found in the Bible (Isaiah 54:17). Here, it refers to the best of Judah's warriors—those who fought against their enemies. If this interpretation is correct, then Macbeth was saying that he felt no less love for his children than any other father. Finally, it has been noted that "the very firstlings of my heart" could mean his friends or allies. The word "firstling" can also be found in Isaiah 52:14 where it refers to those who will be loyal to God during his reign on earth.
