1:17 Matthew states that each period has fourteen generations, but the first and third periods list only thirteen. A legitimate Jewish and Old Testament approach would count David in both the first and second groupings and include Jesus in the third grouping. This suggests that Matthew is probably stressing the gematria (letters representing numbers): The letters in the Hebrew word dawid (“David”) also add up to fourteen. Matthew is highlighting Jesus’ credentials as the Messiah (1:1).
