in the Active Voice, signifies "to cheer, gladden," 2 Corinthians 2:2; in the Passive, "to rejoice, make merry;" translated "faring sumptuously" in Luke 16:19 , especially of food (RV, marg., "living in mirth and splendor"). See GLAD , MERRY , REJOICE.
"to strengthen, to be strong," is used in the imperative mood as a formula at the end of letters, signifying "Farewell," Acts 15:29; some mss. have it in Acts 23:30 (the RV omits it, as do most versions).
"to have," is used idiomatically in Acts 15:36 , RV, "(how) they fare," AV, "how they do."
"to joy, rejoice, be glad," is used in the imperative mood in salutations, (a) on meeting, "Hail," e.g., Matthew 26:49; or with lego, "to say, to give a greeting," 2 John 1:11; in letters; "greeting," e.g., Acts 15:23; (b) at parting, the underlying thought being joy, 2 Corinthians 13:11 (RV, marg., "rejoice"); (c) on other occasions, see the RV marg. in Philippians 3:1; 4:4 . See GLAD , GREETING , No. 2, HAIL, JOY, JOYFULLY.
Note: As "farewell" is inadequate to express chairo, which always conveys the thought of joy or cheer, (b) properly comes under (c).primarily denotes "to set apart;" then, in the Middle Voice, (a) "to take leave of, bid farewell to," Mark 6:46 , "had taken leave of;" cp. Acts 18:18,21; 2 Corinthians 2:13 (in these three verses, the verb may signify to give final instructions to); Luke 9:61 , "to bid farewell;" (b) "to forsake," Luke 14:33 . In the papyri, besides saying goodbye, the stronger meaning is found of getting rid of a person (Moulton and Milligan). See FORSAKE , LEAVE (take), RENOUNCE , SEND (away).
Note: For aspazomai, "to bid farewell," see LEAVE (c), No. 2.
