HAP; HAPLY [ISBE]
HAP; HAPLY - hap, hap'-li (miqreh, lu; mepote):Hap (a Saxon word for "luck, chance") is the translation of miqreh, "a fortuitous chance," "a lot" (Ruth 2:3, the King James Version "Her hap was to light on a part of the field belonging unto Boaz"); in 1 Sam 6:9, the same word is translated "chance" (that happened); "event," in Eccl 9:2,3, with "happeneth," in Eccl 2:14.
Haply (from "hap") is the translation of lu, "if that" (1 Sam 14:30, "if haply the people had eaten freely"); of ei ara, "if then" (Mk 11:13, "if haply he might find anything thereon"); of ei arage (Acts 17:27, "if haply they might feel after him"); of mepote, "lest ever" "lest perhaps" etc. (Lk 14:29; Acts 5:39); of me pos, "lest in anyway" (2 Cor 9:4 the King James Version, "lest haply," the Revised Version (British and American) "lest by any means").
