A harvest has a season. Jesus names the season as the close of that age.
The prophets used sickle language for days that landed on cities. Jesus uses the same farm calendar.
Matthew 9’s harvest of workers and Matthew 13’s wheat and weeds are one field story heading toward AD 70.
The barn is the New Covenant people. The bundled weeds are the old order cleared when that world ended.
You are not standing in an unfinished field waiting for a later sickle. You are wheat already housed.
