1 Thessalonians 4:1

1 Thessalonians 4:1 kaqw.j kai. peripatei/te {A}

The parenthetical clause kaqw.j kai. peripatei/te is lacking in D^c K L Y 177 206 257 623 917 1175 1518 1739 syr^p (and the Textus Receptus), having been dropped either accidentally (through confusion with the earlier kaqw,j clause) or deliberately (as seemingly superfluous). External testimony supporting the clause is strong (a A B D* F G 33 104 181 218 330 1311 1611 1836 1906 1912 2005 2127 it^{d, g} vg syr^h cop^{sa, bo} goth arm eth); internal considerations likewise favor the presence of the clause, for i[na perisseu,hte presupposes the earlier mention of the Thessalonians having begun the Christian life, but such a beginning is not implied in the preceding text without kaqw.j kai. peripatei/te.
