Maranatha

Maranatha - (Easton's Bible Dictionary)

(1 Cor. 16:22) consists of two Aramean words, Maran'athah, meaning, "our Lord comes," or is "coming." If the latter interpretation is adopted, the meaning of the phrase is, "Our Lord is coming, and he will judge those who have set him at nought." (Comp. Phil. 4:5; James 5:8, 9.)

Maranatha - (Webster's 1828 Dictionary)

MARANA'THA, n. The Lord comes or has come; a word used by the apostle Paul in expressing a curse. This word was used in anathematizing persons for great crimes; as much as to say, ""may the Lord come quickly to take vengeance on thee for thy crimes.""

mar-a-nath'-a, mar-an-a'-tha (from Aramaic words, marana' 'athah, "Our Lord cometh, or will come"; according to some, "has come"; to others, "Come!" an invitation for his speedy reappearance (compare Re 22:20); maranatha, or maran atha): Used in connection with anathema, "accursed" (1Co 16:22), but has no necessary connection therewith. It was used by early Christians to add solemn emphasis to previous statement, injunction or adjuration, and seems to have become a sort of watchword; possibly forming part of an early liturgy.
