2 Tesalonika 3:9

3:9 It was not because we do not have that right, but to give ourselves as an example for you to imitate. ¹ 

2 Tesalonika 3:17

3:17 I, Paul, write this greeting with my own hand, which is how I write in every letter. ² 

[3:9]  ¹ tn Grk “an example for you to imitate us.”

[3:17]  ² tn Grk “The greeting in my hand, Paul, which is a sign in every letter, thus I write.”

[3:17]  sn Up to 3:17 the letter was dictated by Paul but written down by a secretary or amanuensis. But Paul took up the pen and wrote vv. 17-18 personally to authenticate that it was his (how I write in every letter). See similar indications in 1 Cor 16:21; Gal 6:11; and Col 4:18.
