That ye may know (ινα γνωτε). Second aorist active subjunctive of γινωσκω. Just as in Colossians 4:8 he had not written ινα ειδητε in verse Ephesians 6:21.

Our state (τα περ ημων). "The things concerning us," practically the same as τα κατ' εμε of verse Ephesians 6:21. See both phrases in Colossians 4:7; Colossians 4:8.
