2 Tesalonika 2:9

2:9 The arrival of the lawless one ¹  will be by Satan’s working with all kinds of miracles ²  and signs and false wonders,

2 Tesalonika 3:17

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

[2:9]  ¹ tn Grk “whose coming,” referring to the lawless one. Because of the length and complexity of the Greek construction, a new sentence was started here in the translation.

[2:9]  ² tn Grk “every miracle.”

[3:17]  ³ 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.
