“You blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.” Matthew 23:26
ἐντός is the Greek word for “inside, within” and occurs 2 times in the New Testament. I found it interesting that, in most translations for Luke 17:21, ἐντός is translated “in your midst” or similar. The translations for Matthew 23:26 were consistent and translated ἐντός as “within.” I am going with “within,” although that wouldn’t exclude the Kingdom also being in their midst. If someone knows better, please let me know.
Anyway, one of the commentaries referenced Psalm 45:13: “The King’s daughter is all glorious within; Her clothing is interwoven with gold.” From what I read, the King’s daughter is a reference to the church. What was interesting to me is how her inside matched her outside. Her outside is a reflection of what is in her heart which has been sanctified.
In Matthew 23:26, Jesus admonished the religious leaders: their inside and outside were inconsistent.
FIRST, be clean on the inside. The outside will follow. It has to be in that order.
“But seek FIRST the kingdom of God and his righteousness, and all these things will be added to you.” Matthew 6:33
