Revelation 2:19

The oldest manuscripts transpose the English Version order, and read, "faith and service." The four are subordinate to "thy works"; thus, "I know thy works, even the love and the faith (these two forming one pair, as 'faith works by love,' Gal 5:6), and the service (ministration to the suffering members of the Church, and to all in spiritual or temporal need), and the endurance of (that is, shown by) thee (this pronoun belongs to all four)." As love is inward, so service is its outward manifestation. Similarly, faith and persevering endurance, or "patient continuance (the same Greek as here, Rom 2:7) in well-doing," are connected. and thy works; and the last--Omit the second "and," with the three oldest manuscripts and the ancient versions; translate, "And (I know) thy works which are last (to be) more in number than the first"; realizing Th1 4:1; the converse of Mat 12:45; Pe2 2:20. Instead of retrograding from "the first works" and "first love," as Ephesus, Thyatira's last works exceeded her first (Rev 2:4-5).
