For you know what charge we gave you through the Lord Jesus.
What charge we gave you ... All of the commentators agree that the words here have a military ring, meaning "the orders we gave you," thus accounting for the variation "through the Lord Jesus."  Paul was making it clear that his orders were actually those of the Lord, a fact further emphasized by the use of the great Old Testament word for "Lord."  As Hubbard put it, "Paul's commandments were stamped with the authority of Jesus, who is Lord, the exalted Ruler of Life."[5]
