Who then? (kai tiṡ). For this use of kai see note on Mar 10:26; Joh 9:36. The kai accepts the condition (first class ei̇̇lupō) and shows the paradox that follows. Lupeō is old word from lupē (sorrow) in causative sense, to make sorry.
Maketh glad (euphrainōn). Present active participle of old word from eu, well, and phrēn, mind, to make joyful, causative idea like lupeō.
