Hebrews 1:1-2–last days of the OLD COVENANT, not the end of this age

Hebrews 1

1  God, who at sundry times and in divers manners spake in time PAST unto the fathersby the prophets,

Hath in THESE LAST DAYS spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;

One cannot separate the first verse from the second.  Last days, throughout the Bible, until the Bible began to change after 1830s, meant the LAST DAYS OF THE OLD COVENANT.
