Japhet Kipyegon Korir (born 30 June 1993) is a Kenyan long-distance runner who competes in cross country running competitions and the 5000 metres. He was the gold medallist at the 2013 IAAF World Cross Country Championships, becoming the youngest ever world cross country champion. He has a personal best of 13:11.44 minutes for the 5000 m track event.
Korir had much success as a junior cross country athlete: he won two team titles and a bronze medal at the 2010 IAAF World Cross Country Championships, then took the first junior title at the African Cross Country Championships in 2011. He was the runner-up at the latter event in 2012.
Korir won his first international medal at the age of fifteen at the 2008 Commonwealth Youth Games, getting a bronze medal in the 5000 metres. He was part of the winning Kenyan junior team at the 2009 IAAF World Cross Country Championships, where he finished fifth, and helped retain that title at the 2010 IAAF World Cross Country Championships, where he came third as part of Kenyan podium sweep. He failed to make the team the following year but was chosen for the 2011 African Cross Country Championships, where he became the competition's first male junior champion. He ran in Europe later that year and set a personal best of 13:17.18 minutes for the 5000 m at the Nijmegen Global Athletics meeting.
Japheth /ˈdʒeɪfɛθ/ (Hebrew: יָפֶת/יֶפֶת Yapheth , Modern Hebrew: Yefet ; Greek: Ἰάφεθ Iapheth ; Latin: Iafeth or Iapetus ; Arabic: يافث) is one of the sons of Noah in the Abrahamic tradition. In Arabic citations, his name is normally given as Yafeth bin Nuh ("Japheth, son of Noah").
In Biblical as well as Quranic tradition, Japheth is considered to be the progenitor of European, and some Asian, peoples. In medieval Europe various nations and ethnicities were given genealogies tracing back to Japheth and his descendants. Religious syncretists later adopted the euhermistic argument that Japheth's memory was distorted into mythical figures such as Iapetus and Neptune.
Genesis 10:21 refers to relative ages of Japheth and his brother Shem, but with sufficient ambiguity to have given rise to different translations. The verse is translated in the King James Version as follows, "Unto Shem also, the father of all the children of Eber, the brother of Japheth the elder, even to him were children born". However, the Revised Standard Version reads, "To Shem also, the father of all the children of Eber, the elder brother of Japheth, children were born." The differing interpretations depend on whether the Hebrew word ha-gadol ("the elder") is taken as grammatically referring to Japheth, or Shem. Further uncertainty about the birth-order is suggested by a passage in Genesis 9:24, which says Noah realized what his "younger" (or "youngest") son had done to him, referring to Ham.
